My lay fix is to simplify the aim controls to use the right stick to engage aim and aim. All that’s coming to mind as an example is Shadow Complex. I don’t see the utility in separating aim from engaging aim if you don’t need to double up on a directional input.
The worst pain is holding the shoulder button while also using the stick on the same hand with very demanding precision as in the EMMI encounters. I put it down on the first one, not worth it.
