How many skills is too many?

[Avatre]

You can have up to 40 buttons on controller before having to switch cross hotbars, using r+l and the wCross hotbars.

Edit: kept miscounting, not in game to check visually.

Technically, you can have 48 different skills set on controller without using R1 to switch sets. Set 1(just because it's the default one) give 16, R2+L2 is 8 more, L2+R2 8 more, then double tapping either L2 or R2 is 8 more for each of those(totalling 16). 16+8+8+16 = 48

Of course this all relies on someone enabling all 3 of the cross hotbar types.
