Let me explain something about tank gear. (ignoring you highjacked an educational thread with ignorance).
I am a MT warrior. I only use 3/8 T1 gear. 8/8 T1 gives around 60 def. This is a 5 man tanking set only as the 8/8 gives more sunder threat. It is shit, and once the death bone -a 5 man blue OMG..... gets upgraded, I will be 1/8 T1 just for stam bracer, and 4/5 deathbone. The belt, and gloves have same stam as T1 and 2x the def.
My cloak, 5 man blue, trinket, onxyia turn in, and brd trinket (which is BiS aoe tanking which pally LOL at due to 25 damage reduction x how many mobs).
BRD ring when it gets upgraded, currently use don ring for tps, dark iron ring.
Next is a blue -OMG not again.... Neck. Medallion of grand mashal morris.
Shield, for def cap guess what, best shield in game til Chromag is a blue, deflector from ubrs.
MC has no MT raiding weapons. Brd blue legs have amazing def and were only replaced by T2. A pally with go deathbone here. Helm, golem helm is used, OMG a blue which i didnt replace till T2.
Your only attept to put up facts was gear availabilty and what is used for tanking. Prob is you came to a battle of wits unarmed.
Your second arguement wad because everybody else does something so that is the best way. Take that approach to economics, so the poor are doing it right cause there are more people living in dept than the 2%who are not?
Can I keep up with pally threat, no. My threat is limited and doesnt scale much with gear. Actually has a chance to go down due to avoidance means no rage, so no threat. A MT war uses 1.3 speed dager and raid buffed auto attack gives 3 rage.
Can I AOE tank better, no. I even have Rag damagw deflect trinket. Aoe packs are always lower level and do little damage, aoe is only thing that matters on those pulls.
Where do I excell? Oh shit buttons, better EH. Due to gear. I am the best role for the hardesy hitting mother fuckas in the game. Plain and simple.
I am currently gearing up 2 pallies in guild that will be aoe tanking certain fights, healing others.
Seeing your lack of knowledge in itemization, only purple > blue, you already showed your narrow mindedness gas is epic.
