I've gotten Titan EX down to a farm, but there's still one thing I don't understand, sometimes 1/10 times the ST can pull hate off MT during the heart, usually when ST is a WAR, maybe using an aoe? It's definitely DPS based since if I am running ST at that phase and much higher geared than the MT I can also pull hate off the MT during the heart stage.

The thing is the aggro meters on the heart make no sense, regardless of who has max enmity, healers or ST the Titan should only target the MT or whoever had aggro before the phase. I thought the titan heart is a separate entity that has its own enmity table.

And irrespective of heart's enmity, "Titan" himself should keep enmity on whoever had the highest before the heart stage, maybe we're talking about enmity fall off where the MT's enmity drops faster than the ST, maybe the ST has some enmity buff on? Any one able to shed some light on this?
