So something I've slowly begun to grow accustom to, and actually generally be accepting of, are healers who stick on cleric stance and do a bit of dps. As I've learned with THMs and ARCs, when your party composition are made of mages, you need to employ flash a little bit more frequently, and do the rounds of individual aggro building.
Tonight I had a strange one, though. CNJ using Fluid Aura to knock mob monsters back that I wasn't directly attacking, which drew extra aggro on the CNJ, took the monster out of my immediate access, and meant that if I wanted aggro back I'd have to compensate.
When questioned, the CNJ said that the tactic was akin to Sleep, and helped take the heat off of the tank.
I responded, explaining that it didn't.
* It strips aggro I've established.
* Any interference by other DPS further strips aggro more quickly.
* I can't recover aggro quickly because it's now outside of my vicinity (particularly troublesome in cramped hallways with patrols).
* If CNJ or DPS take the aggro, because they're squishier, they have to stop what they're doing and focus on that, or I have to scramble to recover it.
The CNJ basically claimed that if he wanted to do it, let him. I pointed out it was a bad tactic even still. After that he became snarky, and then basically threatened that if we pressed the issue more he'd stop healing. At that point I left the instance.
Is this a thing? Because it shouldn't be a thing.
I understand that a confident CNJ can manage their damage, but the problem is that it mucks with the party composition in a big way, confuses the other party members, and undermines the tank in more ways than one.
It was particularly frustrating that after being told to stop by both a DPS and the tank (myself) he refused to.
I'll note though, that I didn't scramble to recover monsters all that much. To begin with I just flashed as the monster came back, or shield lobbed. Essentially running interference as the monster bounced around with uncertainty from aggro to aggro. After the explaination I let him have it and watched what happened, and the proof of what I said was in the pudding.
