it seems that the current school of thought for tanking classes is that all things held constant, the classes should be able to perform the same whether it be main tanking single targets, or tanking multiple mobs with are of effect abilities. I question this whole notion of equality amongst classes.
Firstly, let me say that I do not want it to be the case where a guild's 10 man progression group is stuck on a particular encounter because they lack an experienced Warrior tank, and a warrior is the only class that possesses key abilities to overcome the encounter. (Think DKs and early Sarth)
Having all tanking classes equivalent is like a president's cabinet comprised of all Department of Defense candidates, (no pun intended.) There's no thought or deliberation as to whom to bring. I fail to see how disparities between tanking classes are a bad thing. Certain classes should have advantages and disadvantages over other classes; it's what makes the game interesting.
For brief example:
- Druid Feral tanks have the largest health pools, and suffer damage like a real beast would, take the blows full force, but be a monster to take down.
- Warrior Tanks, with their mastery of the sword and shield mitigate damage through skill and strength, exposing an enemy's weakness and retaliating with force.
- Paladin Tanks calling upon the light to absorb and deflect damage, and sacrifice themselves to keep others from harm.
- Death Knight tanks using the cold of Northrend to their advantage, hardening themselves to mitigate damage, and using unholy plagues and disease to heal and gain strength.
If all classes are equally equipped to be exceptional in all instances, then really, no class is exceptional. They are all the same. So then what's the point of having different classes at all? Specialization, customization, and itemization. These are the things that bring excitement and enjoyment to tanking.
Well, at least for me that is. :P
