Got some heavy salt when I ran as tank last week in alliance C.

Alliance A went in to tank (Paladin) - no problem. I'm a WAR, I like to DPS anyway.

First boss went through no issues.

Second boss was going fine, but all of a sudden the boss swung around to me.
I'm tanking now?
Did A die and I didn't notice? Nope... they're still alive.
Did I forget what stance I was in? Nope... still in Deliverance.
Seems like A simply didn't generate enough hate. Maybe they tried to swap into DPS stance on their own? I dunno.
I walk to the front of the boss, stay in Deliverance, and just keep going.
A stays there too, eating cleaves for no reason... but never gets hate back with me staying in DPS stance...
Ah well, no biggie. Boss dies and we move on.

3rd boss is buy-on-the-chariot, right?
On that one, same thing happened. A's PAL starts the fight, and everything's going fine.
At about 45-50% health left, I end up with hate again in my DPS stance.
I walk around to the front of the boss and continue to tank in DPS stance hoping they'll just take it back and do their job.

Then some DPS in A's alliance starts calling for A and C to stop fighting for hate.
I just stay quiet... it's pretty obvious to anyone who cares to look that I'm not fighting anyone, A's tank just sucks.

Then DPS-from-A starts whining about chariot-boss not being tanked in the centre... because the bomb-AoE (run away as far as possible from boss) causes more damage if boss is near a side.

I find that really suspect. Seems to me that if the boss is near a side, there's more room to run away (and take less damage) where if he's in the middle, it's all equal distance to run away from. I can see advantages to that (DPS doesn't have to consider where they are... just run away from boss). But I can see advantages to tanking him nearer to one side... if DPS position themselves, they can easily run farther away, and take even less damage.

I'm open to being convinced otherwise on this, anyone really care if the chariot-boss is tanked in the middle or not? What are the reasons?

But, in the moment, I thought it was fine where it was and I didn't move it.
Boss died easily enough anyway and we move on.

Moving towards last boss, DPS-in-A starts crying about tank-fights and how bad Alliance-C tank (me) is. I still don't say anything. I don't really care about what some kid thinks.

Last boss starts up, A-Tank starts fight and takes boss again.
This time I decide to relax a bit on DPS... just to make sure I don't take hate off of A-Tank. Whatever, boss is dying fast enough anyway.

But then I notice the boss swinging all around again.
Did A die this time? Nope, lots of health over there... what happened?
Check the hate tables and see that some Monk on Alliance B edged A-Tank in hate and took the boss.
Well, as a tank this is simply something that I can't stand for. Let the DPS do their jobs!!
I flip into tank stance, provoke, berserk, unchained and butcher's block until the cows come home. Boss doesn't move again, and DPS kill him easily... all the while A-DPS is chirping about tank-fights and how bad C-tank is. I'm just laughing at him the whole time.

Anyway... such is the fun of 24-man content
