What we want is the paladin to have Commanding Shout + Kings, and the warrior having Battle shout + Kings BEFORE the fight starts!
I dont know if this is a "common knowledge" but ive never seen it used, or heard of anyone using it before.
Dont do this until its 10-20seconds left until the fight starts!
1. Paladin buffs himself with might and warrior with kings.
2. Warrior use commanding shout, and Battle shout right after.
As the might has more AP than Battle, it wont override the buff and the paladin will keep Might + Commanding.
3. Paladin swaps Might for Kings.
The warrior will have battle + kings and paladin will have commanding + kings.
Hope this helps! You can try this out being in a normal group aswell, does not require arena to work!
