You can't hit the jump button with your thumb on the right stick? Guess you have girly hands then don't you? lol I repeat because you don't understand.
At minimum on the modern controller you have access to L1, L2, L3, L4, L5, R1, R2, R3, R4, R5 a left analog stick and a right analog stick all without moving a single finger from it's default positioning. That's 10 buttons you can use at all times without having to move your hand off another function. Everyone knows a keyboard has more buttons than a controller but access to those buttons is superior on the controller because it's designed to have you use multiple at once so you don't have to lose 1 button to gain another. I played through Elden ring DLC on the steam deck and used L4 for blocking but I must be lying because you're upset I keep proving you wrong and you're desperate to defend your e peen lol. I've also bound jump to those buttons in the past in different games depending on how camera heavy the game is. They're quite useful.
