He may attempt to use Reversal on your Stickybombs, be smart and don't aim directlly at him. He can still be hit by behind and the sides, a sticky bomb over him can deal significant damage, while he's unable to react.
Drogoz is a good counter since he flies and inaras projectiles are hard to hit and specially if you have W.Y.R.M Jets.If you are good at aiming then the direct shot damage bonus may even be better.
Easy way to kill a fernando is to get behind the enemy and hit him from the back which will force him to turn around leaving him vulnerable to champions that were in front of him before,but you will have to be careful of his allies.
