Mace Windu

If i were to design Mace....I would look at the movies of course  clone wars

I would give him a charge force push with the widest radius(comparable to luke) with the greatest length, shorter charge than obi wan

Varpad like duelest could be an activation 15-20 seconds, faster, increased damage, damaged resistance, also the only saber user that can run and block

Lightsaber tracking throw, not a liner throw, but similar to Idens stun droid programming, the saber will attack those within range

Passsive, card related, does more damage to dark side foes 25%

Passive master, like Anakin after so much fighting on the battle field Mace dark side erupts, and he can use shatter point, similar to Dooku find weakness, Mace can activate Shatterpoint within a 15 meter radius, All enemies affected will have defenses lowered by 35%, to Darkside Heroes 45%, this will last 12-20 seconds 

Darkside powers used agains't him effective or not, increases cool downs of abilities 

Health should be 800, no less maybe more with StarCard

Just a few ideas to throw out there
