Best Weapon/Abilty push - Arena

Just curious on some peoples game tactics on the best weapons your team should push for at the start of a slayer game on a few maps.

Coliseum - Sniper/Rockets = Me: Rockets
Rig - Sniper/Caster = Me: Sniper
Overgrowth - Railgun/Camo = Me: Railgun
RipTide - Caster/Beam/Camo = Me: Beam

Coliseum sniper is crucial

Coliseum - Sniper/Rockets = Me: Rockets
Rig - Sniper/Caster/Camo = Me: Camo
Overgrowth - Railgun/Camo = Me: Camo
RipTide - Caster/Beam/Camo = Me: Caster
Molten - Sniper = Me: Brute plasma Rifle
Truth - Camo/Fuel Rod/Energy sword = Me: Energy sword
Grassy version of truth (i forgot the name) - Over shield/Caster = Over shield
Those are my strategies on the maps that i can recall.
