I don't Know

Let's see...
+100% Damage bonus (Since it's a chainsaw, duh)
20% slower firing speed (Same as the Ullapool Caber)
-Takes the primary weapon inventory space
-No random crits

How about this
+450 damage
-50% reduced ammunition capacity
-Does not fire bullets

This is all compared to stock.

(+)
200% Damage on Hit
150% Movement Speed
200% Ammo
20% Faster Spin-Up Time

(--)
Requires Gas for Ammo
Does Not Fire Bullets
Takes up Primary Slot

(+)
+50% Damage to buildings
+100% Damage on hit
+40% Faster shoting

(-)
-35% Moving speed while fire
Takes up Primary Slot
No critical hits
-25 Health points

(+)
+100% damage to players (its a chainsaw)
+Your speed isnt reduced while revved (i feel like a chainsaw would be lighter than a minigun for the heavy.)

(-)
-50% slower revved up time (pulls the cord a couple times and it starts.)
While pulling the cord your movement speed is reduced heavily like a revved up brass beast.
Chance for the chainsaw to break while sawing buildings (chainsaws and metal don't mix well, it could pop the chain off.)
No random crits.
Replaces ammo with fuel, start with 200 fuel.
Lower fuel = slower rev up time.

It should give heavy a speed boost when equipped.
Should have 5 sec bleed.
Range is depleted to melee range.
When reeved up will make heavy go even faster.

If you don’t like my stats at least be with me on a speed boost because it can make heavy’s, sub class, fat scout way better.
