I don't play PVP. My experience is raiding/storyline progression 1. Generally I get the feeling that Assassins are seen as always too squishy, whether as tank or as DPS. 2. In my experience, an Assassins' nice set of defensive skills and self-healing makes it stand up just fine to most challenges. There are a few bosses that make it struggle, but it's a class more uniquely able to kite bosses than any other tank type, so it's a rare and situational issue that rarely causes a real problem. As a DPS class, I find Assassins pretty fun to play, though there is a lot of buff-bar watching to make them max out their damage. That's not something many people appreciate. Oh, and they squish really fast. It might be nice to give them some way to dump aggro other than using their once-per-battle-imperfectly-working combat stealth ability. My one major gripe? I like to mix and match abilities, trying out different trees. The Deception tree is entirely too Surging Charge focused. if you don't want to use Surging Charge, there is no way to progress up that tree without wasting a lot of points.
