Any suggestions are welcome.

Any suggestions are welcome.

Q and W underpowered. Dmg and stat increase too low.

E What will equipping each weapon do except let him do ult? (besides rifle)

In general, I think the MP cost and CD are way too big. He also doesn't have any skills that scale. I like the concept though.

I was just thinking about the skill synergy. Well, the weapons are just attack modifiers.
