Tanks, please use strength gear.. :(

[Nektulos-Tuor]

The 15-20% extra tank DPS gained from going glass cannon compared to full vit should never be the difference between killing a pack fine and the healer running out of mana.

That seems rather foolish.

Bonuses multiply with bonuses, that extra 20% + the extra 15-20% you get from darkside and maim or the extra 30% you get from FoF makes a HUGE difference. "Glass Cannon?" you lose no mitigation from switching vitality to strength. Gaining more health just makes the fight last longer, it does NOT make your healer heal any better. It does not improve your mitigation, it does not suddenly make the mobs on you hit for less.

As for pulls, yes I don't run out of mana with normal pulls and I can heal just fine and even cleric stance. However, most tanks "do not do normal pulls" They pull 3-4 encounters at a time and usually mass pull. 5 seconds is the difference between full HP and dead. Your full HP does not help.

However, doing the following for example does.

Warrior:
Maim+Internal Release+Full Berserk+Bloodbath+Vengeance+Infuriate+Unleash+Overpower+Full Strength Gear. ((Huge combo I know...))
Now you are healing significantly every time your attacked and every overpower hit. You are also doing a good chunk of damage and killing the mobs faster.

Dark Knight
Darkside+Salted Earth+Unleash/Or Abyssal Drain. (Use a CD if needed!)
Now you are dealing significant threat and pushing that damage on the mobs. It does a bit more damage then the Warriors version but has less sustain.

I don't play and have never played Paladin past 30 so I will not comment on them.

10000 and (2000 hps) vs 5000 (4000 hps)

Sustain beats it out every time unless the mob hits for 5001.
