I've messed around on 7 of the 8 classes now, and one struck me as being EXTREMELY broken.
Thief.
Topping off with my highest crit being 8700, with classes having as low as 11k hp, This just seems completely unbalanced.(That's just the opener with poison & a signet). To put this in perspective my highest elementalist crit so far was around 2k. And that was an easily avoidable, telegraphed Giant circle, with a slow falling fang(takes 3-4 seconds, even cripled you can hobble out of it). This is a shadowstep into an unavoidable slash.
With being able to lock you down for up to ~7-8 seconds, with no escape, Running double dagger/double pistol - I found I could take on any single person with generally out even getting hit. 2v1s were very realistic. I did take a couple 3 and 4v1s, but they were exceptionally bad. Such is to be expected, most people have under 5 hours of gameplay under their belt, afterall.
With how much damage, how easily it is to do, do you feel that they are balanced - with only having such minor drawback of being squishy? Have you(as a light armor wearer) found an easy way to handle these guys? What about you medium armored peoples? Do heavy armors destroy them?(I haven't seen very man, the few i've seen were exceptionally bad).
Am I missing some key weakness here? Playing them, I've not found any glaring flaws to exploit. They seem to just be powerhouses, that in the right hands - are unstoppable.
