Many of us would prefer sacrifice very soon. Sparton said it was comming but it was not close to ready. He did say he would look at them moving parts of it up but we haven't heard anything in a while about it. I haven't counted because I keep having to sell off 4 & 5* dupes but I have a ton,around 30, 5* dupes I'd like to sacrifice.
New content and pvp means new characters which I just don't have room for. I'm one of those players that want one of everything. But the that is just not possible in this game unfortunately.
