Played it up to hell level 8..... currently at level 50, and have over 55k hp.... and I still get two shot... switched heroes a few times to see if maybe vampire isn't the best for the job, but..... I honestly think he's the strongest hero in the game. Anyone get further?
Personally, P2P games don't work well. They don't get a lot of players because most people can't pay. Secondly, kred offers don't work very much. My other concern is that it will become boring. It has no spark. I would gladly play if it even worked, and I didn't have to waste time to find a working kred offers to play the higher levels.
