Make sure to bind jump, grapple and other important movement buttons to rear buttons so you dont have to take your thumbs off the joysticks to use them (think bumper jumper control scheme from halo).

I am perfectly comfortable playing multiplayer competitive shooters with joysticks and gyro, fine aim control is a breeze with gyro for me and really the disadvantage playing on the deck is a framerate and screen size issue, I can be competitive even in a game like Xonotic (possibly the most fast paced, aim heavy shooter period) with joysticks+gyro.

I say all of this not to say you are wrong, maybe joysticks+gyro isn’t your thing and that is fine, but it is a comfort and preference barrier limiting you here, not an inherent limitation to joysticks+gyro.
