new Unit - Roach Cannon?

Iam think, many ppl build for fun a Roach Cannon. But when he control this roach ramp good,
so he can make coast.

Many ppl dont use this roach cannon/roach ramp good.

So the other ppl think, he is trolling.

iam personal: i like the roach cannon.

I think it was nice to import the Roach Cannon as regular unit/building like Berta or Tac-Silo in the game.
my small imagination:

First:
A Building like Berta and Tac-Silo.
Build this Cannon, and the roach will build like a tac-nuke on a "Silo".
You select Target on Map an then he fires one shot like Tac-Silo.

or other Idea:

Second:
Build a Self-Feeding Cannon.
You build this Roach Cannon as building but he dont build his own Roaches like silo.
You Have Shild Fac, then you build a Roach and klick right of the Roach-Cannon.
The Cannon is feed the Roach and ready to fire.

In this way it would have to consider whether this gun feed with puppies or Dirt-Bags.

What think about the idea ?

Its called "Big Bertha". Although this version requires more micro. Already exists.

Let nubs keep roach cannoning and wasting metal.

It's called Russian Big Bertha, and because the shooter is always drunk/wasted it's being so inprecise ^^
It's effectiveness is directly proportional to the soberness of shooter && size of clusterfuck and inversely proportional to map size with a high error delta due to the Sun position and happiness of the Martians
