Many people have said they don’t like ADS or the new control scheme. My minor suggestion is to try Bumper Jumper. Not only does it allow the player to constantly have thumbs on the sticks and the ability to jump, it also has zoom/smartscope on the right stick. So it’s perfect, IMO. Give it a try if you hate ADS. It might make you a better player! Well done with the beta, 343.
See my post about custom button mapping to make everyone happy. Show some support there and let 343i know this should be standard operating procedure!
