Tanks are definitely heavily in demand. Although no one seems willing accept druid tanks. So basically prot wars are needed.
Pft, Druid tanks are better if not the same as prot warriors at filling the role of tank.
You're obviously not a healer.
Sure with a Druid tank I tend to use more mana per encounter. But they still make good tanks. Majority of Druid tanks I have played with have held aggro better then warriors on most occasions.
I have to agree that druid is better for tanking multiple mobs, but i would have not say that he's better tank than warrior overall.
