Forum:The level 61 that ruined our game

We had a good game going. We had already finshed about 20 quest with 2 level 15 and a 16. Was it fun for you to come in with your level 61 into our game. What was you thinking? You can kill everybody with a stick and not take any damage with a level 61 in playthrough one. It killed the game for the other three players. Why do that ?
