For what it's worth, I can totally see an AR Controller/Dominator. Something like:
Rubber Slug (Ranged, High DMG(Smash), Foe Knockdown, Foe Disorient)
Rock Salt (Ranged (Cone), Moderate DMG(Smash), Foe Knockdown)
Flash Grenade (Ranged (Targeted AoE), Foe -To-Hit, -Perception)
Caltrops Grenade (Ranged (Location AoE), Minor DoT(Lethal), Foe -SPD, -Jump)
Wide Area Web Grenade (Ranged (Targeted AoE), Foe: Immobilize -Recharge -Fly)
Aim
Tear Gas (Ranged (Targeted AoE), Moderate DoT(Toxic), Foe -Resistance, Foe Paralyze)
Grease Grenade (Ranged (Location AoE), Foe Knockdown, -SPD, -Jump, -DEF(All), Special(Moderate DoT(Fire) when ignited)
Wide-Area Tazer (Ranged AoE, Moderate DoT(Energy), Foe Hold, -End, -Rec)
There's probably some reduncancies or OP stuff in there that could be tweaked. It's just a quick hackjob of Trick Arrow, Arachnos Soldier, AR, and Elec.
