Hello,
since probably every skill has ability to get alternate damage type I spent a lot of time to checking skills to fill my skillset.
Than I started wondering: Why can't we just pick preferred damage type for each skill?

If each skill had version of each damage type that would add tons for possible skillset variations.
I know it would take quite a lot of time to make this. However it is still far easier and less time consuming than adding hundred more skills.
