Should be a total of 4 skill bars

So true.

There are some games out there, that uses the touchpad mechanic, that u can press left corner of the Touch bad and right corner of the touchpad

maybe left corner of the touchpad opens radial for Map options, like Map Toogle, or something else, - so that we can get some slots out of button press slots

and on the right corner are the radial menue for Skills/Tree/Skillbinds a.s.o

Even if they couldn't utilize the touchpad at this moment in time, I would still be very excited about having two separate skill bars assigned to my weapon sets.

Also XBox does not have touchpad feature

Yep that's right. No need to over complicate things.
