Too many make it into content they have no business being in. It'd be alright if they were open to learn but many of them instantly go on the defensive when you prod their bubble and break the silence in chat. Like they're shocked to be interacting with other people. This is toxic and baffling they make it to endgame without human interaction in an mmo. Bringing back proving grounds for endgame content so players don't have to rely on rio when pugging would help, but it's also partly because there's so little danger in regular openworld content that players don't become accustomed to interupts and dodging ground-effects etc.
