Can you add another upgrade?

Right Now there is just Attack, Movement Speed, and Health Regen

Do you mind adding Skill Damage and change the First upgrade to Physical Attack

Skill Damage will improve the Damage of the Skill and Ultimate while Physical Attack improves the damage of the Attack/Basic Attack....

Example : Bunninja is like an Assasin so he depends on his Skills to Take out an Enemy so he will need Skill Damage Upgrade and a Bit of Physical Attack Upgrade because of his Slash and Stab Passive...

Example : Archer is you know a marksman, so he depends on his Basic Attacks, so she will need Physical Attack and a bit of Skill Damage to boost his Skill and Ultimate...

I hope this will be in the game in the future :)
