Do you understand the concept of being carried? Its when you ARE performing bad enough to not complete the dungeon especially when everyone else is performing the same level.
If you die in titan because you cant dodge but because I can dish out numbers high enough to carry 1-3 dead dps. They didnt do anything to contribute to the win.
So by your standards if someone afk's at the beginning of aurum vale. And the other 3 complete the dungeon without kicking, the afk guy didnt cause a fail, so he deserves the win?
