I personally only use 4 hot bar for my controller. I also use w and expanded crossbar.

So hotbar 1 is my main Attack... then hotbar 2 put enchanted melee, some role skill and centre, displacement. Hotbar 3 is w crossbar double tap lt will go left.. I use this to put limit break role skill or cooldown, Potion, sprint..

Hot bar 4 is where I put mount other shortcut such sheath, sign, way mark, minion... and invigorate... for melee job.
