I've never rolled on my alts vs. a guild member by the way. I never had a ZA bear mount.

Although one time, as usual, I brought my shamans in a BT run because we didn't have enough people, and the spell damage shield dropped off trash. Since my shamans were my "guild alts" (My pally tank was my main) I didn't get to roll vs. a member who never showed up for raids (when he did he has constant DC problems and had to be dropped) and just happened to be in the raid at that time. That actually pissed me off a bit since that was his second time in BT and easily my 10th on all 5 shaman.
