Servers are terrible this season - desync, lag, cannot create games, you name it.
Enhanced runes - downgrade and containers, when ?
The short term buffs that work x amount of seconds (10, 20, 30, insert random number here) - why it is not perma buffs ? what is it contributing to gameplay when you have to break your run and cast something every 20 seconds ?
Cow king legs - make into a single item that perma stays in your inventory like belial/azmodan keys (idea comes from Mahitovec stream, so please consider supporting).
NM act bosses - buff shard drop number, now they can drop less than normal act bosses. 2+ shards would be a start into right direction.
Angelic item place - make it bigger (what she said he he he).
