While some tanks are better at getting hate and some plain out suck at it, hate control is not just the tanks job.

If the thm pulls hate in most cases they are not doing thier job properly. The DDs job is dmg output, dmg avoidance, and hate control, pulling hate mean the DD did something wrong. There is a hate bar for dd I think this sums it up pretty well: green = dmg the mob, yellow = caution slow dmg, red = STOP DMG, blinking red = YOU SCREWED UP. That is what I tell my DDS in my ls. I have some tanks which hold hate better then others, but in the end if a thm pulls hate on ifrit for instance.. it will not be the tank getting yelled in most cases.
