I'll be honest, this makes absolutely no sense to me. This is a group mode, it is intended for players to team up and form groups, so why are half of the competitions based on a singular players progression? I like the the Raids challenges, but the others seem out of place for a mode that is entirely based around a group of players. Level achievements I have no problem with, but it should include all team members rather than a single player in my opinion. First 5 man team with all players 1500+ total, 2100+ total, etc makes much more sense.
I agree with this 100%
