Thanks Meenesfeja! The healer I play with uses Physik (sp?), not medica, at this time, so it's safe there.

I'm lucky to have my healer in the same room as me when we play together, haha. She alerts me *before* I lose aggro that I'm losing aggro, which gives me the impetus in time to switch targets in her defense. I lose aggro most often to DPS. If I lose it to the healer I can get it back quickly and easily. It's nearly always the DPS that strip it back, and it's usually because I haven't had the chance to build enough aggro. Or, actually, from what I've now read above, it's probably more that I haven't built enough enmity quickly enough because of unnecessary time delays due to combo-ing from the get-go (Shield Lob > Flash x2 > Combos as opposed to going straight to savage blade straight away.)
