Bit OP don't ya think?

I think you meant to say "fair and balanced"

BOLT CUTTER:

This could be an interesting anti-spy weapon since really the other anti spy weapons are the Pompson, the Short Circuit and the Southern Hospitality which are alright weapons for the most part but aren't really seen too often because of more viable alternatives.

PROS:

+80% damage bonus against cloaked targets (i.e. 117 damage)
(This would reward engineers for tracking down cloaked spies, but wouldn't insta kill cloaked spies unless at health lower than 117)

Crits will be rewarded based on health dispensed by dispensers (probably around the range of every 300-600 health dispensed = 1 crit for the Bolt Cutter. The dispenser being destroyed will give the crits much like the Frontier Justice.)

Crits gained by dispensers will only be used by pressing M2
(Since engineers use their wrenches for much more than just spies, it would be unfair the make them use the crits while trying to upgrade their building. Binding the usage of the crits to M2 will make it much easier to save them for when the time is right.)

+100% damage bonus against sappers
(Basically just takinging down sappers in one hit)

CONS:

+50% building vulnerability against sappers for all buildings
(It wouldn't be very good to have this weapon be the "instakill spy weapon" so naturally there should be equal punishment for not taking care of spies well enough.)

+30% damage penalty against disguised targets (i.e. 45 damage)
(This would counteract the damage bonus against cloaked targets by doing less damage against spies out in the open. Essentially what I'm envisioning is taking the spy down a notch in ways that require the player to be effective, i.e. when a spy is cloaked. This would make it so that crits would only just kill a full health spy, however wouldn't kill a overhealed or a kunai spy with health.)

-10% building speed on dispencers
(This would make the ability to gain crits from dispenser just a liiiitle bit more difficult. Not by much, but just something to balance it out.)

No Random Crits
