I cannot stress enough how the way group achievements work need to be changed. You don't know how many trifectas I've done where the same person would die, or I never die and I'm at the will of someone not intentionally dying. Devs, can you make it so if I (Me personally), do not die during a HM run...I will in fact get the achievement for the trifecta. If you have a problem with someone in the endgame community and they tell all their friends to gatekeep your clears, then you will NOT ever get the easy achievements that you deserve. It's so bad that some people won't even group with people who already have the clears because that person may or may not be as hungry to win as the rest of the group.
TLDR: Make trifecta achievements personal so I can leave after I get it. Tired of knowing content like the back of my hand and not having the clears I deserve.
