You can also control which hotbars (either regular or cross-hotbars) are active when your weapon is sheathed versus when it's drawn. You could set a hotbar with out-of-combat actions like teleport, plus whatever attack you use as an opening move to initiate combat and have that hotbar display when your weapon is sheathed. Then have a different hotbar with all your attack skills show once your weapon is drawn. That would give you a full two cross-bars (including L2+R2/R2+L2) worth of attacks without needing to take up part of that space for things like teleporting, calling a mount, etc.
