Loz and I talked about this on Monday night. I honestly feel the "seasonal resets" have killed this expansion for me. I got my Heart to lvl 47 in early April by really maximising the weekly gains. If I'd kept going it would have capped out at the end of April but on Wednesday there will be some mechanic to let a returning player leap forward and catch up in no time. My item level will be similarly trivialised through updated WQs/dungeon rewards at the same time.
I'm sure this always happened to some extent but it feels far too prevalent and in your face now. My account is active and I may well log in again but it is tough to find the motivation tbh.
