I know what you mean OP, number of Tanks dropping after first wipe is rising. Instead of people trying to figure out a solution to preventing a wipe again they just leave and its always the Tank the leads in dropping from the dungeon, this is assuming he even stays in the roulette as the dungeon loads up.

I don't call players that wipe bad, I call the players quitting bad. Too many times I get players wanting to abandon on first wipe instead of figuring out a solution to prevent the wipe. Bad players arent going to improve if you aren't willing to work with them.

Rage Quitters or Quitters = Bad Players
