I, like a lot of other Halo players, am a Bumper Jumper user. I have been since Halo 3, and I am very comfortable with the layout as it it enables me to perform most of the essential actions (such as turning and meleeing, or jumping and aiming) without taking my thumbs off the sticks.
Optimize the Jet Pack for Bumper Jumper
In Reach, my biggest complaint about the layout was jet packing. It’s nearly impossible to control a jet pack while aiming (without using claw), so I hardly ever used it.
My suggestion is, make jump double as a jet pack button. Make it so when you jump, you can then hold down the jump button while you are in the air and it will use your jet pack. You would still be able to use the armor ability button for it if you chose to do so, but this will really help Bumper Jumper players.
I’m not sure about any of the other new abilities yet, as I don’t know what most of them are, but PLEASE be smart and make the necessary changes.
Be Smart with Each Button Layout
Another one I can think of is the portable shield. I think the best solution would be to make it so that it toggles. So, with Bumper Jumper, I could toggle it on and move around, then toggle it off, similar to sprint.
Button Mapping Please!
Button mapping would be nice too, but I think it’s a little late for that. However, please consider it for a future patch possibly.
