It’s way to fast.
Every weapon kills faster, movement speed is higher, and so on. Halo 4 was already fast for a halo game, between sprint, the low respawn delay, etc, but it was bearable.
In fact, it’s so fast, it barely feels like halo, and a lot of the skill is taken out. It’s become “Who shoots first wins”. You don’t have time to react, respond, and use positioning and tactics to turn the table.
I had high hopes for the TU, and though it is balanced, I can’t play the game. It’s simply does not feel like halo anymore.
EDIT: I am NOT talking about kill times. They are merely a factor.
EDIT 2: I have been playing halo since CE, and it has never felt this fast. Please don’t tell me I haven’t played the games, I have.
Also, here’s a good example of why being this fast is a bad thing: http://img856.imageshack.us/img856/9646/1370318244186edited.png
