How convenient! I proved you wrong and you dismissed it with a stupid argument. I knew you would say that. You're using the same logic as flateathers. I'm pretty sure you're one IRL.
You want data? Go check KeyboardNinja, Dipstick and Bant's work on damage mitigation and theorycrafting, Banderal's data gathering on pvp mitigation and Hottie's pvp tanking guide.
I'll gladly help people who wants to get knowledgeable but I have no respect for know-it-all dense people.
