Here is a simple WAR setup for controller that uses the least amount of buttons and has easy access to critical functions.

First lets set up some macros:

(Off da Chainz)
/micon "Unchained"
/ac "Unchained"
/ac "Berserk"
- double tap this macro in Defiance to go Unchained and then Beserk,or
single press in Deliverance to go Beserk

(Raw Awareness)
/micon "Raw Intuition"
/ac "Raw Intuition"
/ac "Awareness"

(TomaMercy)
/micon "Tomahawk"
/ac "Mercy Stroke" <t>
/ac "Tomahawk" <t>
- this macro mercy strokes a weakened target while the GCDs are still in cooldown, else it works as a normal tomahawk

Now go to Character Config> Hotbars> Cross> General and uncheck "Use pethotbar".

Then go to "Set Selection". Uncheck "Auto swift when weapon sheathed/unsheathed".
Then check "Enable customization when weapon is sheathed" and make sure Hotbar 1 and 3 are checked.
After, check "Enable customization when weapon is drawn" and make sure hotbar 1 and 3 are checked.
Now tapping R1 switches between hotbar 1 and 3 and skips the premade pet hotbar!

Next go to Character config> Hotbars> Cross> "Enable expanded controls" and set the (R2+L2) and (L2+R2) both to cross hotbar 2 left

Finally the actual layout, I personally use a Dualshock 4, so your mileage may vary:
