I'm surprised they axed KotH. I felt they really improved it in Halo 4. Making hill "life" based on a set number of points it can give was a great idea. Keeping hill lives short made the game less repetitive. Pair that with not being able to pick up grenades from corspes (most of the time) and it was much better than halo 3. I get they have lots of playlists and dominion is similar, but it's a classic that got the face lift it needed so why trash it? They obviously invested some time into making it work. Give it more than a month.
It really doesn't make sense to me why they got rid of assault and KotH, but kept oddball and flag. They all came from the same place, why arbitrarily cut them? At least we can still make KotH customs. RIP Assault.
It'll be back, im sure. I'd rather they axe Team Reg eventually though because Regicide fills an FFA role and doesn't get dragged down by a fool king.
