I know what you mean, I am tempted to use a controller. I know I will perform better with one, but I am stubborn. I put in too much effort to improve on csgo to just switch back to a controller.

I'm sure I will have fun on halo no matter what input I use. It feels really rewarding outfragging my cousin who is a god on controller.

My chance of winning a game is like 50 percent. A lot of people playing h3 right now grew up with it. Even though I'm a competitive person and always want a win, csgo tought me that some people are just simply better. I don't tilt at a loss. It's a game, fun should be the priority. If you are not enjoying the controller experience, don't use it.

I reccomend setting your keybinds so that your fingers rarely leave the wasd keys. There is no movement inaccuracy. On a controller your thumb doesn't leave the left stick, so you are always on the move making yourself a hard target to hit.

Don't aim at the head! 3 to the chest and then 1 to the head. I naturally want to aim at the head with a mouse, but halo is a different kind of shooter.
