I've just finished the beta content second time round as a Berserker this time, mostly using a 2h axe I found with 85 physical and 85 ice damage. Wishing I'd specced into Tundra for it, though Howl is probably the most useful skill I have alongside that first skill from the Shadow tree for mobility. Rushing into the middle, Howl to weaken and slow enemies, fight until I've gotta actually heal and rush out again, maybe criss-cross with it a little for lifesteal. Seems pretty effective, though I still die now and again when I get cast interrupted and can't rush out in time.
Surprisingly, this makes goblins the most threatening enemy to me - ice archers slow my cast time, demolitionists and slashers both interrupt casting, so this harms my mobility greatly and using a 2hander my attack speed is already slow without being frozen. Most of my deaths have been to groups of goblins.
Outlander first time using pistols for close combat+crossbow for sneaky business and many glaive skills. The Outlander feels a lot more damaging than the berserker, though that comes down to all my +crit and crit damage enchantments (he crits reliably for 1200+ with the crossbow, my berserker's top damage was 709 on a howled enemy). I found basically no enchanters playing with my berserker, over four different servers, whereas my outlander on his own was practically wading through master enchanters (I didn't even realize enchanters couldn't always do three enchants until I happened to notice the little titles, thought the town one was uniquely terrible)
Overall, ton of fun, looking forward to the actual release. Most people I know are getting/have got/are seriously considering getting it, so I daresay there'll be plenty of people to play with, and if the PAX 2011 video I just ran across is still to be believed TorchED will be released as the fully-featured in-house development tool not a half-broken piece of stuff like the Creation Kit for Skyrim ended up, so mods will undoubtedly increase the replay value yet further.
