It's cause job balance is borked and the fun has been sucked out of events. I have a 3 song bard that can do most events no problem but I got sick of only ever playing it, and being treated like crap when I did play it. Frankly support jobs are a pain to play because everyone feels entitled to yell at you if you don't play perfectly.
Now I see people shout for an hour for a bard for an event I could do but I'd rather level up my goldsmithing or something because I just don't have fun in pick up groups anymore. Abyssea was a good time, the game was chill there was content for all kinds of players, these days its "BE PERFECT OR DIE" and, frankly, I don't have the patience for it 99% of the time. I know I can't be alone.
Honestly, the devs need to up drop rates in easier difficulty levels a bit, so that people can lower the difficulty a bit and still have a chance of getting something more than a chapter. The game is supposed to be fun but the grim drop rates at "normal" and below make it so it doesn't feel like there is any point in doing the content at all unless it is on higher difficulties and at higher difficulties it's not fun anymore.
If the devs think that they are keeping players around by artificially extending the life of this content by making it no fun to do... well that's a really really crappy plan. Abyssea proved that giving plentiful rewards and having fun content that encouraged some job diversity gives life to the game.
I'm okay with like 1 event being "hardcore only" but right now I feel like every event requires a near perfect set up of a handful of jobs with perfect gearswaps etc. and it's just not fun.
