I was recently talking with a "friend". She was doing a VH with a member in her guild who got killed randomly(ok not so random, the members a rogue) and was complaining about it. I asked the question of who was tanking,it was a warrior or dk I don't remember, who was healing, A pally.

It irritates a lot of people and me when people don't understand class mechanics. Pallys are amazing healers. Pally s don't have a lot of multi target/aoe healing. Healing the tank out duties healing the rogue. A warrior is going to hold great aggro on one target, But anything more is quite stressful. Anyone who has played the game should understand basic concepts of class dynamics before yelling and being upset and snotty. And I am certinaly not placing the blame in any corner but maybe the death your so upset about could be your fault for not focus firing, not watching aggro levels. Theres many other answers to examine before assulting someone on their play style.

To do a quick recap.

Tanking:

1. Warrior single target and burst 2 or 3. highly based on rage.
2. Druid best mix of both imho, lowest mitigation, but high health and armor.
3. DK alittle low on holding aggression but 2 aoe aggro grabs and tons of tricks
4. Pally the king of all aoe tanks right now, Great on aggression
