Saving or not?

[Wupti]

I disagree. If you use your ultimate before useing your rocket you can land the combo if you are good with aiming the ultimate. Good heavy tank players should be able to do that reasonably often.

Using your ultimate first will make it even harder thanks to the animation. You should only hit when they don't care or want to bait you. Airship simply can kite it too easy because its too mobile. Your only hope is a point blank hit duo to over aggressiveness or with a teleport.
Remember we talk about lane here
