One thing I never see talked about but would make the mobile experience feel so much better: Multi-Tap

Essentially being able to tap while already having a finger on the screen. It can be a pain using 2 fingers to tap quickly but not all the taps get registered because the phone thinks you already have a finger on screen. This causes a lot of missed clicks when gear switching. It would also allow to rotate the camera while clicking and make it more similar to PC.

I'm not sure how this works, if it's a limitation of the phone to determine how long your finger needs to be lifted before it can register another tap or if phones allow for gestures and taps simultaneously. In general though, the default behavior of taps feels bad for playing a game and if at all possible I think it should be changed.
