No, the PvE crowd can do it if they are willing to force themselves into doing PvP. It’s not like I can run Heliophage Advanced Hardcore 100 times and complete the lore challenge. It has to be done in PvP.
Which is the problem.
It is not, nor has it ever been, a question of effort (which is really just a roundabout way of calling PvEers lazy, since, by that logic, if we were willing to put in the effort, it wouldn’t be an issue; once again, I have put in the effort on other characters; the point is that I shouldn’t have to because it’s forcing me, and other PvEers, to spend a not-insignificant amount of time in a mode I would otherwise never play in order to get access to content that isn’t even supposed to be “elite”; it’s not like it’s Angel of Death; it’s a friggin’ lore challenge). You’re conflating the idea of doing something personally distasteful with exertion/work. They’re not the same thing: eating a piece of feces doesn’t require a lot of effort, but it’s certainly going to be extremely distasteful for a large number of people.
The entire point of the game is to have fun. The lore challenges are supposed to be for everyone who wishes to play the character. Mode specific lore challenges actively discourage players that dislike one mode or the other from playing a character by forcing them into playing what they do not enjoy in order to access everything provided for that character. The reason that only PvE players ever bring up this argument is that the devs have this incredibly lop-sided design mentality that is perfectly alright forcing PvEers’ to run through a gauntlet of PvP matches to get a similar reward that a PvPers might have to spend a single PvE solo mission earning.
Now, because I have brought up the whole issue of “fun”, just because you find it fun does not mean that everyone else will find it fun. The entire point is that the character and everything that entails should be accessible to everyone, not just people that enjoy a specific mode. Furthermore, if making it so that everyone can enjoy the process of getting something decreases your own enjoyment of getting something, that’s tacit acceptance that a significant part of the reason that you enjoy getting that something is because other people are unwilling to do it, which doesn’t really help the community at all. In fact, it’s pretty friggin’ toxic.
It still absolutely requires PvP because you have to hit enemy battleborn. Which is the fundamental issue.
The devs should have figured out by now that they need to have lore that can either easily and quickly be accomplished in a specific mode (to minimize the amount of time people spend in a mode they don’t wish to be in) or more difficult/time consuming lore that can be accomplished in either mode.
If you honestly believe that lore challenges need to be “hard” to get, I kindly direct you at the many “challenges” that require you to go to all of the effort of playing a game with a specific character. Lore challenges are less about challenging you than they are about encouraging certain tactics/maneuvers and linking activity to background story.
