I pick the second worst after the light attack spamming guy

Fake tanks, and fake healers. But I see mostly fake tanks in my experience.

I had a dungeon recently where the guy was "guys I am a fake tank, but if we can't do it i will just leave" that attitude stinks imo because he is basically admitting without shame that he was too lazy to queue up like everyone else and if it does not work he is perfectly happy to leave and make his team wait AGAIN for a tank.

I voiced my disapproval to him but he just didn't care at all.

Speed run guy because he never, ever, ever asks if its ok for a speed run, just zooms off into the distance.

I prefer to stay with the group and ensure that all those adds he dragged and released back onto us get dealt with and any weaker group member doesn't get too frustrated.

Thats if he's even halfway good, if not I just walk over his body as we go past if he's waiting for a res.

The fact that I have to spend a week non stop running a dungeon for that piece of equipment I have probably deconned a dozen times over but need one now to try a new build.

Fake tanks, especially in vet dungeons. That's why I usually queue with a real tank to not worry.

Fake DPS is worse than fake tank.

The people who vote to kick you for no apparent reason.

I'm still salty over that even though I know I shouldn't be, but seriously I wasn't doing a single thing wrong! And I get randomly kicked just before the final boss when I was pretty much carrying them through on a horribly made character.

I chose to vote for the speed run guy, but really for me it's a toss up between both that and the fake tank for what annoys me the most. Like someone else said, the speed run guy almost never asks, and I'm getting tired of being in a dungeon where said guy shoots off and leaves the rest of the group to deal with the trash mobs he leaves behind (and in the instance of the pledge I ran yesterday, the healer up and went off with him and left the DDs for dead - even better when we all wiped on a mini-boss because the mobs decided they wanted to up and join in and we were left overwhelmed).

I think it would just make things a little easier, not to mention it'd just be plain decency for someone to say upfront that they want to do a speed run at the very beginning. Saves a whole lot of time and confusion later on when people start running around not knowing what's going on.

Then the fake tanks.

Had a PUG in nCoS the other week - a tank and myself joined when the others were up to Velidreth and the first thing the tank says is "I'm not a real tank, pls kick me." The group leader tried to initiate a vote kick but sadly it didn't pass. We ended up clearing, thankfully, but it was still annoying nevertheless. At least he was honest about it, though. I'll give him kudos for that at least.

People not knowing how to read. I explain said mechanics in all Scandinavian languages, English, German and sometimes I will go to the extreme and get Italian translate too. but it seems like they can't read chat no matter what you do and they keep dying to stupid mechanics. 900cp my butt.

Alternate between the 3 roles having now made alts for each and to be honest they are all frustrating one way or another. Least frustrating though is speedrun as they are usually half competent.

Fake tank can also be a pain, but fortunately not come across them too often in Vetran and in most normal its a non-issue as I can self heal and shield as needed.

Low DPS is a pain though if I am in the other roles, just makes things slow and take ages. More so when spamming something like force pulse between heals is causing me to do 55% of group DPS (run earlier today)

As a healer, I will bring up the rear, so any speedrunners get no heals.

That said, in pugs, I 'get' why sometimes the tank charges well ahead - in a pug it is often the only way for the tank to grab initial aggro and get the fight started on his terms. I have noticed that commonly. In a coordinated group, the tank gets buffed up then everyone holds while he gets the fight started. In a pug though, his next best choice is to simply charge in and hope to get things going before everyone else shows up.

I like pugging on my healer. Hate pugging on my tank.

could only put one but most annoy me, fake roles, the guy who tries to do the dungeon in a min, and peeps bragging

The speedrun guy in normal dungeons. Normals dungeons are where people are trying to do the quests. Speedrun guy has no consideration for anyone else, and doesn't care if people are able to complete the quest or not.
