i would not start playing again untill there will be new gameplay features to explore and master and i'm pretty sure i'm not the only one like that. i play the game for the gameplay itself, right now i've seen most of it.
only when new refreshing features will be out, people will start coming back to try it out and master them. no items/tc boosters/cosmetics is any interesting for those who seen it all.
variety is the king.
