Oh I hate fluid aura, I whm and I have never seen a legitimate reason to use that skill. I also tank and nothing irritates me more than a whm that feels the need to immediately use it due to pulling aggro because their spamming of medica. I asked a whm to please not use it he said then don't lose aggro. I let him die the next time he did it and another in our group initiated votekick on him. Try me, I know plenty heals that will join in progress party.
