Can't see myself playing either of those with the 3 second global cooldown.
I'll probably finish off a couple of tier 1 rewards and just go back to ic.
Apart from the last test they proposed, I don't like any of them.
Not sure what is there to test on Templar or sorc? You simply won't have the skills available to survive solo, and even in small groups it will be sketchy at best.

My main is a stamblade sniper, so I will probably roll with that one and let my magsorc & magden alts rest for awhile. I will actually have to replace one AoE skill that I tend to spam in some situations for something different however.
