[spoiler]Burning Maul light attacks take no super energy and instead grant super energy like the battleaxe.[/spoiler]
This is the PvE buff. We can all come to an agreement that the spin attack is completely useless in PvE compared to the slam that takes less energy, and makes fire tornadoes.
Which leads me to the PvP buff:
[spoiler]Fire tornadoes funnel opponents.[/spoiler]
This is a needed buff, as this super has become a laughing stock for it's inability to hit opponents that stay in the air. It needs to be able to counter that by letting fire tornadoes from slams pull opponents down and incinerate them.
