some random quickcast things i noticed, if you see more post them
paladin:
can tele with medi(could do this before, required high apm)
can tele with hf(before the best way to use hf was to activate it during server tick that checked for it, just makes it braindead easy to do it now)
can "shiftsmite" your head without animation, so easier to punish druids. i.e. spamming smite hotkey lets you char stand still, and will only smite when enemy is on top of you, actually rly good change imo
can tele with auras to keep benefit on your team(i.e. conc on your zon 24/7)
didn't test conv, some auras have the 2sec delay so might not work for these type, don't plan to use it so didn't bother testing it
sin:
with warrior out she'll use whatever skill is on your right click when you spam tele, aka mindblast off cooldown
some bad things:
weird delay when spamming certain skills like auras, makes your char stop moving, has a built in delay to prevent it
can't bind mousewheel
only tested for a few mins in single player, there's a lot of bugs so not sure if it's single player related or not
