I agree.
Some of the lore was just super grindy and had no challenge. If it wasn’t that they are tied to the XB1 achievements, I probably wouldn’t have done them all.
Despite some of the complaints, I loved the fact that Ernest’s lore was so easy - I was working on Alani’s riptide for weeks so this was a nice change PLUS I’m not good at PVP so I hate the PVP ones as I know they will take me forever to get at the detriment of my team.
As for Master the characters, I’m going to say no. Not everyone has hours every day to work on leveling up the characters to Level 15 - if anything its a very time consuming process. I’ve only got 13/28 of them there. Will be doing all of them, but don’t foresee that being anytime soon.
