New class and Weapons idea

I had an idea from playing other FPS games and I feel that this game lacks something. How about an addition of a Perk as well as some new weapons.

The Mechanic:
Can provide heavy defense for your team with light and heavy machine guns. Gains experience from dispensing ammo and getting kills from turret.
- Has 20% damage bonus for LMGs and HMG.
- Travels slower than other perks.
- Max health and armor boosted by 25%.
- Can set up a LMG sentry turret (only one per Mechanic and replaces weilder.)
- Can dispense ammo for free for other players (they must have the weapon they want replenished selected to refill ammo.)
- Starts with a SMG, The A180.

added Weapons:

SMGs
A180 (American 180)- a low-powered yet high RoF SMG

HMGs
M60- Has high power w/ moderate RoF. Uses Ammo belt therefore has long reload time yet very large ammo capacity.
