Umm, where is Assault?

So my close bud got a copy of Halo 4 recently, and invited me over to give it a whirl. Yeah lucky me. Anyways, i was just browsing around in the lobbies and gametype settings, and shebang, Grifball (yay?) Whatever.

Ok wheres assault? What, its not here? but thats impossible, grifball is based on assault!

(now looking frantically for assault)

still cant find it!!!

and as i sit here, blood boiling at the realiziation of a classic gametype forsaken for bloody grifball, i start to really wonder what on earth 343 has done with this game, and the inordinantly unnecessary levels they have gone to pervert so many aspects of the game. seriously, why? why?
