Please stop, there is no sane reason why a tank should slot points into strength instead of vitality. You having less or the same hp as a dps is not an effective tank build because a dead tank does zero dps.
If you say that you hold hate better then you must never flash or taunt , seriously if you do your threat generation rotation properly you will hold hate and once again when you die due to your low hp your threat generation goes to zero.
It is not a healers responsibility to spend an insane amount of time and mana keeping you alive when you choose not to talent properly, it's like healing a dps that thinks he is a tank.
In conclusion is you want to play a dps class then roll one otherwise learn to play as the role you selected which means you are there to take damage not cause massive damage to mobs and die in the process.
