Not only that, considering has it own EULA and copyrighted, unfortunately modifying content is not possible, not because the devs are not able to, but it'll get the project down.
The developers must take the permission to modify any client-related code/w.e from EA first.
The only thing I find that should or must be balanced or in other words, nerfed is the spell Revenge.
It's broken, causing PvP to be way OP and unbeatable.
