rented this for the week. Loving it, but I think that the crusader is a bit OP for the game, At least what I've played so far. He crushes monsters. Just made lvl 22 last night after only 5 hours of gameplay.
Have experimented with demon slayer, liked it too. Its similar to Rogue in DiabloII.
Don't like the wizard too much. Weak at low levels.
