Gyro is so much fun. I'm usually not interested in playing the hard carry role because all they do is rightclick creeps and put points into their boring passive skills for the first 20 minutes. Meanwhile, Gyro can actually shred people early on and is geared up with 4 super low cooldown spells, ranging from extremely powerful (rocket barrage, flak cannon) to terrible but amusing (homing missile). In team fights, you just aim your ult and homing missile, pop your rocket barrage, flak cannon and bkb, and charge into the enemy mob yelling FIRE EVERYTHING. Great hero.
I fuckin love gyro, almost always crush the enemy team on him since I figured out how to play him.
I always just max flak cannon and bully the enemies out of lane with it every time it's up, it's just free harrass without creep aggro which compensates for gyro's poor attack range and low starting hp. I don't care about lane equilibrium on this hero.
Once they run out of regen they play like pussies and the lane is won super hard.
Flak cannon and rocket barrage make it so risky to dive him (stand your ground n fight), and once he's level 6 just dropping a calldown on top of yourself usually turns into a double kill for me and the support even if they kill me.
I don't level missile at all until I need it (one point) to zone out people while taking their tower and stop deny attempts. (it's really good at zoning, and I like it for chasing later on but stats make gyro so much scarier and tankier)
Just max rocket barrage, max flak cannon and tons of points in stats.
Phase-> early dominator for stacking (maybe a bracer or drums first if I'm having to fight with my team early) -> bkb-> mkb-> butterfly or satanic
I love how you can get so much farm on him (and so many levels!) in so little time between the ancient stacking and flak cannon in the jungle. With all the points in stats you are super strong by lvl 15-16 ,and you hit 16 early.
You can play sooooo agressive on him and turn on every dive and every gank attempt.
Midgame is just farm farm farm all day with tps for when the team wants to push or a fight breaks out.
It's also great how big an advantage flak cannon gives you in teamfights, it's so much easier to position yourself if you can just hit any creep or any hero to do your thing without heavily committing right away.
