I think I remember another part of that old post. It was about the wishing pool. Since Mat can make Lewis use the wishing pool for his own sake, does that mean that at some point we can get additional uses of it, or even unique effects by telling others what to do?
Another thing is the Harem transformations. I already mentioned that the removal of normal Harem Mag was kinda a bummer to me since while I liked the whole getting Mag as a loyal follower via backstory invasion, I'm not a big fan of essentially replacing characters completely... unless they're, like, awful and deserve it I guess. So is that how all harem options are going to be?
