The Electro-Wrench: An offensive engineering unlock

Pros:
-Buildings hit with the electro-wrench upgrade 40% faster
-Buildings also upgrade twice as fast (2 upgrade 'points' per 1 metal)

Cons:
-Repairs take twice as long and twice as much metal

Thoughts? Improvements?

Sounds like it cancels itself out.

IT'D BETTER LOOK DAMNED COOL IF IT'S THE SAME AS THE WRENCH.

I think they will use a weapon to do with engineering like a welding gun or something, but in my eyes i'm 100% sure it will be long range (a nailgun is obvious) and may not even replace the wrench but add on as the primary weapon (wrench is perfect tbh , high crit and repairs)

On first sight I think it will be quite effective in promoting the so called 'nomad engineer'. Sitting behind your sentry wacking it will be less effective (you'll probably repair slower than it is being dealt damage) but quickly building expendable sentries is encouraged. I like it.

Not too sure bout the slower and less repairing thing.  I think that could be too much of a can for people to want it.  If its slower would that also mean its slower at removing a spy sapper? Not a good con to have.  Its an interesting idea but you could reverse it and have it take longer to set up but cost less to build and repair (20% less or something), and have it taking 30% longer to build and upgrade.  Also like the Medics gun make it so it can't crit.

You could also give it a second function that if you have a full 200 metal you can right click it and use all the metal in one go to upgrade / fully repair your sentry/dispensor/teleport.
