I posted a question above about my shaman getting smeared on pulls with a bard. First, this isn't a problem for group content, as the shm can handle a few rounds without dieing, but this has always been the case. I just plowed through it. However, when farming raid content for augs the shaman gets wrecked on pulls. I noticed something that I did not notice before, that may offer insight on why this keeps happening.
When pulling on the bard, I noticed that as soon as I get back to camp my HP goes from 100% to 92.2% every time I get to camp. I have even circled around the camp a few times with no HP drop, and then return to camp and get the drop. The shaman heals immediately (because I'm in camp) and then takes aggro before the warrior can engage in Tank mode, and against raid content it dies immediately.
Why does my bard HP drop once at camp? I'm not getting hit on the pull, it happens with non-caster NPCs, and the percentage drop is the same every time. Does it have something to do with the Ward?
