Feeling forced to cap at the citadel is an extremely bad game mechanic
Literally every clan I've ever been in, there are people who want the clan citadel to be max level, so they guilt-trip other clan members into trying to cap.
Maybe this is controversial, but I play this game because I wat to have fun. Getting horrible exp rates and a mediocre reward while capping is the opposite of fun.
This mechanic makes me just want to give up and play solo forever, which really sucks because I have met a lot of cool people through clans.
