Question for those who play Sandrone with a PS controller

I absolutely adore Sandrone and her gameplay, but I have a little problem I'd love to discuss. When I play with her on my controller, it's doing a lot of strain on my muscles because I need to move right stick to adjust the image, press R2 and hold circle for charged attack. As I have small hands apparently ( yup, a fragile gamer girl :P ), it's pretty much hurting the muscles when I have to use thumb for my right stick and index finger to hold the circle. It's for the first time I have this problem with anyone's gameplay. Does anyone else have the similar problem? If yes and you pulled for her C1 which adds 3 more hits (so you don't need to press R2 into it so much (which adds on the muscle strain even more), was it worth it? I'm genuinely considering pulling her first constellation purely for this mechanical problem on my already hurting hand. Thank you very much for your answer :)
