I've been having great fun with my 2H dwarven noble warrior. The little tank just smashes EVERYTHING. And keeps going. Even if the rest of the party is wiped out, provided he's got some health potions. Using Berserk (combined with powerful blows) is just plain frightening.

Plus the fact that greatswords clip into the ground when on his back amuses me to no end.

Early on I dropped everything into str and dex, str for power and dex because initially I couldn't hit anything. Later on when I started dying too much I focused on con a bit.

Ability wise, I find taunt isn't so great. I went for a dual-warrior party, using Allistar as a second (His magic-canceling abilities are useful), with Lelliana and Wynn backing me up. Lelliana seems pretty decent in a fight, although it's a pain to micromanage her into backstab position every time, and she seems fairly useless with a bow.

So most of the time I just use the 'rush in and kill everything' strategy ;)
