Then, we would have the following master strategy: Jetpack while looking down. Impaling, impaling, impaling, impaling, impaling, robot death, robot death, robot death...
Yeah... kind of like that. Like the idea, though.
Well if you looked down, you may or may not hit one of the enemy legs the enemy's blade would definitely hit your head.
If you look straight ahead they could still parry you even if you're not swinging.
