So, today I queued up for a nice and peaceful trial roulette as tank (paladin, it will be important later, believe me). I always have 'Party in Progress' checked, to help parties who lose their tank, for whatever reason. And for the first time in a pretty long while, my trial roulette queue pops as a 12 minutes in progress trial. I load in and I immediately see Ravana. Frowning, I ask the chat what happened and the only answer that I get is 'mechs happened'. Two of the dps leave while that is being said, so we wait for two new dps. Finally, I pull, as MT. The OT was also a paladin and he had Sword Oath on when I loaded in, so I assumed I was going to be MT. First thing I noticed as soon as the fight starts is that the OT is doing absolutely... nothing. Not even kidding. His character was even turned away from Ravana, and he wasn't attacking, moving, anything. Then aoes appear on the floor and he barely moves and takes the hit. A minute later, he types in chat "shield", during a slaugther cast from Ravana. I ignore it, not knowing what he means. A good 30 seconds+ goes by and he types in chat "oath". So I type "hm...what?". Silence.
Another full minute goes by and he types again 'shield oath' in chat. So this time I say 'Can you make a full sentence, please?'. I had shield oath on, I didn't understand what he could mean. Then I see him switch to Shield Oath himself and I kind of get the hint that he wants to be MT? I think? But I've been watching him! I knows he barely attacked the boss and has been getting hit in the face by every single mechanic. So, I don't feel like letting him be the MT! But I was wrong. Because next thing I see in chat from him is : 'shield oath, turn it on'. ?????? And I promise you my Shield Oath was on the whole time. It had been on since I first loaded into the instance. So I couldn't help but say 'It is on, you weirdo'. Then I finally didn't hear from him again.
Until his mechanic comes around. The one that focuses on OT and deals a good share of damage and the OT has to stand away from the party to not cleave everyone? Yeah. Somehow he managed to be the OT, by just enough hits on Shield Oath, and he stands where everyone is stacked, cleaving everyone. Until I yell in chat to get away from the party and he runs to one of the barriers of the arena and we just hide behind Ravana again. We end up killing him just fine and I got all comms at the end.
It wasn't really awful or anything, but it was... so weird. I don't understand what happened or what he was trying to do, to be honest. Oh well *shrugs*
