I just recently gave up on my static that was trying to prog O12S. They had been stuck on M/F Savage for over a month. 3 of us (including me) have been to Final Omega a few times and we knew what we were doing.
But the overall the group as a whole couldn't get it done. Either the healers didn't know how to shield/heal for Fire III or the tanks was mess up the last phase, or we just didn't even manage to get LB3 up at times which I found absurd.
When I would try to bring up issues during non-raiding times, the group never had much to say in the Discord channel almost like they were offended I'd try to have a discussion about problems. And I always got the sense that people just never tried to do more research as to how to do some mechanics better. So week after week we were just wasting our time and I got sick of it.
Anyway, anyone else been through this? It sucks giving up a group, but man it was going freaking nowhere.
