Can the assassin update be next up after the mages?

They said they want to tackle assassins at some point, since there are some problems (Akali is sort of a mess), but based on some of Repertoir's comments, I don't think they're going to do another mid-lane class next. He said they're trying to give all players something, so we've had Juggernauts (top), Marksmen (ADCs), and now Mages (mid). I would guess that supports are up next, since it's been a while since supports have gotten anything (besides the sightstone upgrades, which aren't that big a deal), and also it would be a good chance to look at their itemization given the overlap between mages and supports with FQC. If not, I would guess tanks, where they address both support and jungle tanks
