This certainly is one hell of a good RPG game.
I have been playing it for a couple of days with a buddy of mine on Steam, though I haven't stated this on GamerDNA yet.
We are playing Guardian (Defense and Nature) along with Slayer (Hunter and Warfare), and the combination is devastating.
Guardian is by far the best Tank combination in the game, and Slayer is definitely one of the best DPS combinations. We annihilate everything that comes in our path, and the first Telkine proved to be no threat.
We are in Act II at the moment, and by the speed of our progress, we are almost finished as well. It is going to take a while before we complete the game, and we play on going beyond to the higher difficulties, so there is still much work that needs to be done.
I will keep things updated on GamerDNA, for those who read my posts.
