especially when heroic dungeon difficulty

I feel like the main problem is also that people arent incentivized for being lenient, if anything the opposite is true, especially when heroic dungeon difficulty is where it is compared to wrath.

Wrath taught everyone that they could enjoy a heroic dungeon every once in a while, while here wow gold in cata, a tank may have to pop more CDs on trash than on boss mobs depending on the group make up (and yes i've had groups in the dungeon finder with my paladin tank involving nobody who could CC.

These groups sometimes end up getting frustrated, understandably so, and the blaming begins until someone either rage quits, or decides to try and boot an offender.

Thats not really fair, especially when it happens right before the final boss where all the goodies are handed out for completing the dungeon. In fact, if someone is summarily kicked, I think they should get the final rewards compensation for the portion they did complete (the gold and valor/justice points).
