The O.C.D. Wrench

Engineer melee

This weapons firing rate and repair rate increases, as your buildings health decreases making it really easy to repair your buildings, but this is bad when your buildings are at full health since when they are at max health they have a slow firing rate, and has a slower repair rate and also when your buildings go down. So you have a 50% faster firing speed, a 25% faster constructing rate when hitting the buildings with your wrench, and the pros are basically when your buildings health decreases your repair rate and firing rate increases, and this goes up to a 65% faster firing speed and a 45% faster repair rate making this really really good on defense if you need your buildings alive and you don't have time to build more if they are getting damaged really hard. So when your sentry does down you already read the part were you gain a 50% faster firing rate, and 25% faster construction rate when your sentry goes down, and the down sides are that you have a 25% slower firing speed, and you have a 20% slower repair rate when your buildings are at full health.

Tips:

This is mostly good on defense since you can repair it really really fast.

This could be used as a alternative to the gunslinger as battle engie, with its faster firing rate when your building goes down, and they use their wrench as a last resort.

You could not repair your buildings and tell your medic to uber you, so you have a faster firing rate meaning that you'll deal alot more damage, and pair that with you have stock uber (I'm assuming) Then you are a unstoppable.

Stats:

+ When your buildings health decreases your firing rate and repair rate increases

+ When your buildings go down you have a 10 second 50% faster firing rate and a 25% faster construction rate

- 25% slower firing speed

- 20% slower repair rate
