Currently, I'm a healer main (SCH) and I'm looking to get into tanking after encountering a very nice tank in DF who explained what the other side looked like. I understand that tanking is about both being able to survive and being able to hold hate, as well as PLD being about avoiding damage and single target tanking while WAR is more about soaking damage and AoE tanking, but I don't know much more than that.

First, are there any other major difference between PLD and WAR? Do you have any recommendations as to which one to try first?

Also, is there anything you would like to say to a new tank, about ex common mistakes, oft overlooked abilities, etc?
