You know what really grinds my gears?

or worse, they joined at the final boss, but they were locked out of the fight and end up winning the item.

neither of those things are their fault. they don't get to choose when they get to in-progress and they didn't ask to be locked out.

[Nahaara]

a misaligned clutch or worn out synchronizer really grinds MY gears.

-Outside dungeons:

1) People undercutting in the MB like if there's no tomorrow.
2) PFs looking for charity.
3) PFs getting people with bonus when it clearly states "no bonus, farm".

-In dungeons:

1) Healers that won't DPS and spend their time jumping around or standing still looking at my health bar drop to 90%, then spamming heals.
2) DPS that don't know how to DPS. Alternatively, DPS that think they are tanks and they go ahead pulling trash or bosses. I occasionally let them die and they don't say anything. (They better)
3) Tanks that won't pop a CD ever, tanks that don't push more DPS. Tanks that don't know how to pack a mass pull of trash.

Healers that don't DPS. That really grinds my gears.

People who join cross-world party finders with only two other people in them, express their amazement that the party didn't fill two seconds after they joined, and immediately drop to seek a different party. UGH!

Melee dps who charge into a swarm of enemies, overextend, and don't even try to get out of the pack that turns on them like a school of piranhas scenting fresh blood.

Dps staying out of my line of sight when they're taking hits. So much tunnelling.

When MB undercutting wars break out due to people's lack of patience. Something that was a stable 80k per item and sold at consistent intervals, suddenly crashes by 50% due to one individual selling tons at half the price which resulted in tons of people of undercutting them to compete and thus the price is now stuck at a much lower rate for the foreseeable future :c.

When people ask that content needs to be nerfed...
...when it doesn't need to be nerfed.

Please stop. Do mechanics. It's really not that hard.
(Well, I guess apparently, it is.)

[Fernosaur]

My Egi taking manual commands as suggestions.

Bahahahaha, this made me crack up!

"Yo Garuda, Contagion dat shit."

"I'd love to but I'm honestly not feeling up for it, maybe in 40 secs, k? k."

[Meillquei]

When I'm in a Duty Finder group and I get a tank who spins the boss around in circles for no apparent reason.
