Yes, because the population is SO huge right now that every mob in the vicinity is long since dead. Those wolves are rank 25-30 on their own, and they aggro. They're also blocking the route to Owls Nest, so you can't help but annoy at least one of them. Well, guess what? I'm rank 22, and being completely flattened by them. Also, my class is a mage which has a really horrible VIT-HP ratio. Three guesses how long it takes to be killed?
The bomb is constantly assailed by fire elementals at rank 35 which can nail me in two shots. Yes, of course I should be able to complete this quest, how silly of me.
I'm guessing you've got a rank 50 under your belt, or I'm pretty sure your attitude would be different. Yes, fine have quests or missions you can't solo. Thats normal, and expected of an MMO. Event quests though? Nope. They're time limited events which should encourage as many people to participate as possible. This isn't it.
I can scarcely name any MMO which doesn't make their event quests fully accessible across all levels, so why should FFXIV be any different?
There's a difference between 'playing with others' and 'leeching ashes'. I could happily plant myself in Owl's Nest and just pick up ashes while other people do the dirty work, but that's hardly getting into the spirit of things, is it?
