Anyone here plays S4 League?

Umm...so if you guys don't really play that much...could you guys like, train me or something (on and off, that is)? Because as it is, I really suck at the game.

I'm looking at a Sniper/Assassin playstyle.

I'm thinking of maybe...

DM/BR
Rail Gun
(Might be pretty risky for BR...)
Plasma Sword
Revolver
Invisibility/Block
(Depends on map)

Chaser
SMG
Plasma Sword
Revolver
Invisibility/Anchoring
(Depends on map)

TD
SMG/Semi Rifle
Plasma Sword
Revolver
Invisibility/Anchoring
(Depends on map)
