Didn't expect the next change log to be so huge. Very nice.
I've played about 4 different characters all the way to Defiance Bay on PotD.
Cipher is just obscenely OP. That stun move is just brutal and honestly even Grieving Mother is ridiculous with her abysmal stat distribution.
Fighter was just dull all around. But I did make the mistake of trying to play a DPS fighter... yeah, not too many active abilities to take advantage of.
Barbarian is pretty solid. Despite what a lot of people were saying he was pretty damn durable most of the time. Worked as a solid backup tank even without much invested into gear/skills. I probably would have finished the game with this character but for role-playing purposes I just couldn't really connect with this guy's story.
Rogue is the one I'm currently running and I might restart since I want to take advantage of some of the new patch features. This guy is probably the weakest class starting out. With all the other classes I was able to take clear out everything but the bears/wolves in the starting area. Not too many active abilities, but he does involve a good bit of positioning and synergy with party members to work well. He doesn't really feel nearly as powerful as Barb or Cipher at level 6 though.
I have 178 hours currently logged... I might never finished this game at this point. I just don't know what class I want to finish with.
