Hiding this behind the break, out of courtesy to those readers who’ve just started DA2:
Jay finished DA2 tonight…
…and immediately started another playthrough.
Dragon Age 2 is more tactical than a lot of RPGs. The combat can be fast and frenzied, and to get by on a Hard or even Nightmare setting, or even just the later stages of the game, you can’t get lost in one-on-one combat. You have to think instead about how best to manage your entire party all at once, on a split-second timeframe. In particular, that means setting up attack combos amongst your party members (Anders and Fenris, for example, or Aveline and Isabela, etc.)
That’s why, of the three classes, I find that the mage class is probably the easiest to play as a beginner, because many of your spells are a) really freaking powerful, and b) target multiple enemies at once.
