Barrier is also very viable when your up against melee champs

Pros- Great burst and lategame, also provides harass for melee's, also provides a solid disengage
Cons- no hard CC and can become useless if falls behind

When you engage, you want to Rocket Jump (for slow), Rapid Fire, Explosive Charge, stack Explosive Charge, then when they're low enough (or you're afraid you might die), Buster Shot them
