With the Elementalist I have the combo of Winter's Grasp followed by Stonefist. Two keys, hitting them at random gives a 50% chance of getting the right order. Why is my success rate lower than 10%? 
Haha guys, wish I could like every single post in this topic! 
Some of my favourite things to do in MP:
1. By far and large, I do the console pressing key *a lot*. One would think I'd rebind it after so many fails.
However, when pressing it, it is a momentous occasion. I press it, then somehow it doesn't want to be pressed again so I spam the button a few times, I close it and accidentally open it again. And again. And again. Until the team is dead and I look like the a massive idiot.

2. Another one I love is failing to revive someone. And not because of reviving bug but because somehow I get the icon for revive but somehow fail to activate it. Meanwhile, a barrage of arrows are eating at my health and the task is made even more difficult by my target moving away, probably trying to get away from me, preferring to die in peace rather than suffer my inept attempts at revival. 
3. Dying to dragonlings because I cannot retarget at them. Oh, that one is so good. Starting at 3 full coins, getting surrounded by a pack of dragonlings, yet despite continuous efforts to target them, and not the dragon, sending bolt after bolt, and broadsides at it while the dragonlings eat my coins, bring my health down and eventually kill me. Izzy is just too bloodthirsty for the dragon. 
Personal favourite from my last night's games with Gya and Badger: Dying *while* Walking fortress is on. Beat that one, fellow scrubs!
