Everyone claims the sunsinger has the best neutral game, but, the range on the stormcaller melee is insane. Like really really insane. Plus I am a huge fan of the arc bolt grenade or what ever it's called. Throw that into a control point and make sure you slap on the ability that makes your grenades chain extra lightning damage and you will wreck shit. Also use the zhalo supercell to finish or stragglers. Lightning AoE for days!
