The title says it all, I feel that we should be able to have an option to change how to access our WXHB from double tapping the corresponding trigger to holding both triggers. I know you can just clone both hotbars to have the same skills set and you can then activate it that way, but then you're getting rid of 16 slots that could be used.
From my perspective, I'm coming from playing with Mouse and Keyboard in this game. I've played with 45 keyboard buttons mapped (15 mapped + ctrl and shift modifiers) when I didn't have an MMO mouse, and I've played with an MMO mouse with 36 buttons mapped (12 mapped + ctrl and shift modifiers).
After playing this way for a few years I'm just now trying out controller, and some jobs feel squished with only having 32 hotbar slots available by using cloned hotbars on a controller.
Just my two cents that more customization of the UI/HUD is almost always better than having less.
