Well... you've been probably generating aggro from healing aswell - I'm sure you're aware that WHMs can generate a lot of aggro, from stuff like Regen-ticks or Cure III alone... every DPS also has aggro dropping tools - I dont know wether or not you used yours, but if you didnt and the casters did you have another reason for their aggro to be lower.
Now, maybe you really did generate most of that aggro by dpsing - and its not unlikely for the DPS in runs like this to be shitty, we've all been there... but I feel that this is a good time to remind everyone that aggro-meters are only giving you an idea about the dps you're putting out and that there are perfectly fine reasons for a healer, specially a WHM with those big heals, to be at the top of the aggro-list in such a fight - healing-aggro and aggro-dropping tools being only two of those.
