Modus, you have 5 pieces of t5, why not use the 2.4 badge legs? They're more health with almost no mitigation loss. And unless threat is a major huge concern of yours, you can also change to +stats on your rings. It's another 0.4x% dodge and 100 health.
Another thing is that you gain more from buffs than warriors. You get more dodge from gift of the wild/food/scrolls and more health from stamina. (paladins get 1% dodge per 25 agi, warriors per 30 agi). My avoidance set can beat you in avoidance, but I'm only at the t5 level really (guild has only gone into BT once seriously and only first two bosses down) and your armor/health beats me.
In a way, I do agree with Worldie, most of the extra healing you need is mostly just going to be overheal, and thus you don't take any significant amounts more of damage. The main reason paladins seem to take more damage is they're taking more mobs and/or a lack of proper debuffs on the mob. If you're having a paladin tank but no warrior is putting improved tclap on the mob, you're taking upwards of 20% more damage. But this isn't the complete answer, as warriors do have an advantage over us in TBC. I wouldn't be too worried about it though, as it already looks like things are being fixed in WotLK.
