Being bad in this game is no excuse, I honestly don't see how you can be bad, without deliberately trying. You only have a handful of skills, one rotation, 2.5 sec global cool down, and all you have to do in any dungeon is dodge. That's it. So if you're bad, it's because you want to be honestly. This game is made for casuals and people that have never played a mmorpg before. So it's been made SUPER easy. I can't stress the "super" part enough. So yeah deliberately being bad and not taking all of 4 minutes to learn one of these basic classes then yeah, kick em.
