Do you think that their will ever be a system which just can be used that doesnt touch the BattleSequenceManager.cs file ?? I do love this Plugin deeply even if I have not done much lately in my personal project.
It's unlikely I'm afraid.
Most of the plugin directly manipulates how the battle sequence manager determines the level of enemies you're about to fight as well as intervenes with how rewards are calculated at the end of a battle so it's highly unlikely that this could all be done without touching the BattleSequenceManager :/
