Hobohob for engineer

[HoboHob]

So yeah, I like building stuff (and sapping enemy structures) so I figure I can best help the clan by being an engineer (at least until I improve my game).
This is an intel tower I built today:

And a wall to keep those nasty greens out:

Outside the wall was a trench, but I didn't get a pic of that.
While I was in the game the greens didn't get a single intel cap. Try as they might they just couldn't break my tower.
