Certain sub bending abilities should only have 1 or two abilities to balance the mod. Stuff like Combustion and lightning should have one or two abilities mainly combustion because combustion is OP within itself basically being a walking TNT cannon and is deadly at long range having multiple explosion based abilities will only incourage making firebending characters to use that element more often than that of actual fire bending because it is so accurate and has an aoe and is long range. In the plugin it is even OP in terms of damage. In the show it only had one use and it would be best to have it like that in the mod. Bloodbending even is an OP style of bending, can have a little bit more because of its restriction on the full moon.
