Druid vs Warrior

[Quokka]

Right now I have a Feral Druid (bear) with gear 533+ and a friend has a Paladin in equil gear.

I feel like i suck up more healer mana, than he does? And my self heal feels very weak compared to the paladin.

Did anyone feel the same or does it change once Getting HC/Raid gear.

Because I was thinking about rolling a warrior because there is more utility while tanking.

What do you think should I stick with my druid or rerole Warrior since I'm going to be the MT? Cheers
