The new mission table is so nonsense that there’s hardly even good addons for it, because it’s so dumb and complicated the addon makers largely didn’t want to deal with it. None of said addons suggest teams of regular followers from scratch, at best they can suggest additional fill-ins from non-named units once you’ve added at least one named follower to a mission. I run three different addons that are supposed to tell me the chances of a mission succeeding, one of which has been discontinued and only works through janky workarounds, and they’re all still wrong sometimes.
Terrorwing Assault, the mission in the screenshot, is one of the worst. I’m not sure why a mission for 350 Venthyr rep had to go so hardcore, but something about it just seems broken and I almost never do it. It’s not worth the lost health and tying up my followers for it. When I do I have to assign every single one of my heavy hitters who hit as many targets as possible.
I really, really hope that they don’t do the same for the inevitable new mission tables in the next expansion, but I’m sure they’ll double down and make it even more obscure and complex.
