Two things which I wished were changed:
Shared Pain: Should not apply when going to graveyard, it is a major pain when people wipe late and kill those already running, if people need to due to technical issues, if some want to safe their super, others wanna go to the entrance etc. etc.
And in the end this also regularly kills people when some are running back to get loot, others are already done, likely it should not apply at all outside combat.
Hot Foot: Would be more fun if it was a jumping debuff like the Ricardo one (with a short time to dodge it by moving once you notice it). But it seems to apply, like, every single second of the dungeon, requiring constant movement of the whole party on higher shards.
Now depending on the type of controllers moving back and forward or sideways during 30mins (on Rift that means pressing the thumbstick back n forth, continuously, while playing, which is just stupid; touchpad users got a major advantage here) or more is just exhausting and no fun at all. Up to the point that we do less dungeons when there were some hot foot in it… It makes me physically dizzy sliding like that for a longer time, it feels like playing a game on a broken screen, vision not being stable due to the movement. I flatout hate it the way it is right now.
