Call of Destiny: Advanced Titanfall.
I feel like Treyarch, Sledgehammer and Infinity Ward don't understand that the core gameplay of Call of Duty just does not mesh well with the gameplay/designs of other shooters. It just doesn't do extreme movement, classes, abilities, weird map features etc. well.
Call of Duty is basically the Counter-Strike of consoles. Its supposed to be simple, basic and pure. It works best and is the most enjoyable when it doesn't have any fluff and is simple and focused.
But keep trying guys. Either you'll make it work, or kill your own series.
