Thanks kaeko, I should be more polite when posting so I apologize for that peptaru. I'm not trying to come off as an elitist asshole, I'm just trying to post accurate and helpful builds/tips.

I know people see HP stacking as a wow thing and don't want wow in ffxiv but even in wow they had phases that changed what tanks used, like togc anub you had to have an offtank with maxed avoidance to pick up 4 adds that reduced your defense every hit requiring you to either dodge, parry or shield block every attack thrown at you. Just because HP is most useful right now doesn't mean SE can't be all "Dev1666: We changed the way damage from monsters is calculated." or fix shield in 1.21a.

I also play whm alot as well as tank every current endgame fight, and I like the breathing room an extra 500-600 HP gives. Just feels safer and two whms can practically out heal any damage done to a tank if enmity isn't an issue.
