VKAllen .... you need 6 tiers for your class, within the 6 tiers you can assign your skills/abilitys..also 
Mimic....needs alot of explanation... where do you copy from, seeing as tho u cant copy skills what do you copy ect?

Double Wind Step... boost by 25% movement speed

Shepherd's Throw... id say does either 20% wep damage or cooldown is 5 mins

Spirit Weapon ... needs re-thinking, maybe you have +10% proficiency with all weapons

sub-class... merchants cant identify so its either change name or sub-class, and we havent talked about carrying weight so im not sure what units you mean...

but before u think about awesome moves you need to have all 6 main tiers set our with there abilitys. =)
