Tx, a most appreciated response! 
I am getting a “Nerf kuni/cloudkill, buff money shot” feeling from this post. And I approve.
The main reason I do not agree with these challenges is that is singles players out of otherwise team based verses matches. Galilea, Alani, Wiskey Foxtrot they will all forget the game type the moment they see there prey. Its even worse to be on the receiving end of it all. Sometimes people just say screw it and leave. My friend did this exact thing and the ambra left the capture match after 2 minutes and 4 deaths. I probably would have just sat in nova myself at that point.
Any chance you could just convert the Kill challenges to " Win against X, X many times?" It would keep with the spirit of the game, that being teamwork, far better than the " Kill X, X many times" or even " Get X assists, against X, X many times"
These kills and future assists challenges sadly will mainly encourage the lone wolf mentality. The mind set of " I’ll sacrifice myself to kill/damage X in hopes that someone else can kill X for my challenge progress". That’s just simply how these challenges end up being met and its why people get all the more frustrated at failing to kill/assist against X than normally.
But what if its “Win against X, X many times”? Then the whole 'Lone wolf" mentality quickly gets curbed. Players will emphasize on team work, possibly even more than usually when they see X on the enemy team. Gaining wins is best through team work, so if that’s tied to the challenge via “Win against X” then players would get to continue to play as they normally do instead of going Rambo and sacrificing themselves to try and Kill X, as they currently are practically forced to do as of now.
@JoeKGBX, wouldn’t mind hearing how you think about this as well. The whole replacing " Kill X, X many times" with " Win against X, X many times"
These are good ideas to be sure and not that far removed from what we been discussing so far. I think we might be on to something! 
I’m delighted to hear a response and happy to see you’ve found it. I wouldn’t be terribly surprised if such ideas were already being tossed around in the think tank over there, but it couldn’t hurt to make sure such ideas are known.
I personally find its a fair compromise. It retains the flavor of the challenge “X having a vendetta against X” with out impeding on the game’s teamwork by encouraging people to sacrificing themselves to try and kill someone else, which would impede the rest of their team’s chances of winning. Which is how I strongly feel that " Kill X, X many times" currently encourages.
Everybody wins, would be my theory.
Wish me luck guys…I’m still need 13 more Ambra kills at the moment. I bet most people avoid picking Ambra because of being targeted by 2 specific characters…and don’t forget she got nerfed not too long ago either.
My Husband and I have talked about how we wish this was the lore challenge already. It would just make more sense and, as you said, lead to teamwork to flat out win the match instead of constantly hunting them down. I think logically, it should be win 5 matches against X, to go in line with the “Play 5 matches with X” lore bits for some characters.
let’s not forget abput toby either
I love the idea of promoting faction VS faction play omg that would make for some sick challenges! It would promote more in game chat discussion as well as more pre made groups of 5 XD
Example: Lead a team of Eldrid to victory against a team with one or more LLC members.
That would be dare I say Badass!
Well Toby is kind of a different case. Double Kill is not perticulerly hard especially when its literally what Core discharge is ment to do ( Kill/ burn down large enemies) It dose still lend to that solo mentality though, “Hey why did you steal my kill you A hole I needed that for lore!”
Still its not to bad seeing as you can go out and find others for a pre made and then work on lore together online then at that point it is just a matter of finding the opportunity. Personally I think Incursion is where Toby should live as he kicks so much butt at it if you have a good handle on him.
The last thing this game needs is more premade teams of 5 playing in public servers.
Why not change it from “Kill Ambra 25 times” you change it to "Kill Jennerit Faction 25 times"
That will make it easier but still mite take some time.
The problem I am having is not enough of Ambra at all. Making it based off of Assists or Kills will not remedy that problem. I think, if a better solution that actually addresses the problem does not present itself, that we should all be awarded all kill-based challenges for lore pieces. I will break my issues down like this:
- I might not even to get to play as Alani, as she is a new character and is reasonably popular, my teammates might pick her before I even get the chance to. (Minor Issue)
- Even if I do pick Alani, I am completely reliant on my opponents picking Ambra…something I have no control over. I do not like that on principle. I should not have to rely on someone who is not on my team in order to fulfill MY challenges. (Primary Issue)
- Lastly, Ambra is no slouch. She can be tough to fight against and I can have my chances screwed by having bad teammates. I have actually played a game where my team surrendered before I could even kill Ambra once. I was upset at how my team screwed me hard on that one. (Minor Issue)
I hope this problem is resolved in a manner that pleases as many people as possible.
Yet another idea I can get behind. I like this idea quite a bit. 
I wish they change these kill X character lore challenge to kill X faction challenge instead
Since alani needs to kill ambra just change it so she needs to kill any jennerite faction and increase the kills to 30 or 50 as it be easyier to obtain the kills in pvp even add an assit could help too
Honestly I think the game needs more
the whole Idea of Battleborn is based around Teamwork! People working together to achieve a common goal.
Getting beat by pre mades? Well that is because teamwork is a force to be reckoned with.
But I’m getting off topic. The point is challenges lore related and otherwise should promote teamwork not the lone wolf mentality.
I’m fine with premades, but match premades against each other. Not randoms.
I think I might start premade taunting you guys. Ambra + assassin. Oh hey come fight me for ur lore, bro 
-rath jumps out and deadwinds you, I end 0 deaths- bahah
I love the Idea of Lore around hating Ambra and how that relates to Alani or Galilea.
I feel that while the reward structure (Lore) makes more sense at the end point, the execution would be best expressed at the Command Level, such as Titles on Ambra Kills being globally tabulated.
A middle ground wouldn’t be out of the question.
1 Title achieved on 25 Ambra Kills (possibly a separate Title for Assists against Ambra), then Galilea and Alani Lore checking for Title acquisition (if there are multiple titles, each may check for a specific one).
