I personally don't mind having to sit every now and then, I'm just glad to be part of the raid.
In response to Uggy's post, I can definitely see where he's coming from, but I think Bar's just trying to solve this the best way he can. Not a perfect solution by any means, but he's working with what he's got.
If being on standby is a big probem for some folks, could we just have designated days where they will have a spot for sure and then days when they can just assume they won't be coming? And for those who don't mind being sat, they could just stay with the current system?
