no invasion slayer in halo 4

Invasion slayer is probably the most worthless game type right now(IMO), I really don’t want it to come back. It isn’t near as fun or as challenging as real invasion(Which I desperately hope comes back in halo 4) and from what i have seen online, its hardly ever played anyway(from what I have seen). I do hope that they bring the anniversary playlists into halo 4 as well, that would be awesome. what does the community think regarding invasion slayer in halo 4?
