Leveling through PotD and Frontlines has kind of made me hate the playerbase

I had an arse in Susano fight for doing an LB on DPS when it was like at 10-ish percent, it didn't dawn on me most of the party was dead.

It's the duty finder that makes people this way. Sure butthats exist anywhere but I played XI for years and didn't run into half the rude people there. Without a duty finder it takes more time to get content flowing though.

With great power comes great responsibility. This is how the game was built, but like others said, go with premade groups with like minds if it bothers you a bunch.
