I recently used the Gyrocopter for the first time and I must say, he was an extremely fun play.
His Flak Cannon ability seemed to work great for farming, allowing my basic attacks to target everything around me in an 800 range aoe. (works nice in team fights too)
I soon noticed however, that if I activated my Rocket Barrage skill with Flak Cannon up, the Rockets seemed to ALSO target everything in the 800 aoe. This leads to my question, what exactly does the Flak Cannon apply to? The two guides sported at playdota.com don't specify, so I'm asking here.
Does Flak Cannon apply only to my basic attack? (was I wrong with my impression that it upgrades Rocket Barrage as well?) Or does it apply to other skills, if so which ones and how exactly?
