While reposega would be cool I hardly find it as the number 1 spell whms need in the next update. The difference between having sleepga(2) and reposega is the sleep duty. When you reposega, not only do you have to continue to watch the mobs you just slept but also still be a good whm. Do you really want to be healing a party/alliance when you could have 5+ enemies ready to pound you down. I'd much rather ask a blm to keep an eye on the sleeps rather than the person who is supposed to be keeping me alive.
