i saw my XP pts dropping from 97pts down to 48pts, then all the way down to... 1xp.. atm. is it some bug or i'm severely penalised for being overly supportive of my clan's assists? thanks in advance to any advice.
You get full XP for the first 50 challenges that you help with. It decreased from help # 50 - 75 then after that you get 1 XP. This counter resets the next day.
