I have only played warrior as far as tanking goes. In my free company static we have several derp PLD who try to tank for us when i go dps.

Somehow, they lose hate on spiders in phase 1 and 4. To me it doesn't seem difficult to hold them. However every other attempt the blm or whm gets nommed in the middle of the phase. What are they doing wrong? How does pld keep aoe hate without overpower?
