I wasn't going for more than Energy with different numbers and inverted bars. I would have used Energy, but Heat is more appropriate for a machine. Like Rumble, both kits are directional and if you can simply make them turn around...

In my opinion, Corki's ultimate is crap (at the moment). It does too little damage at all stages of the game. It feels like a bad version of Mystic Shot - and Mystic Shot even scales better (due to being physical damage, having a higher scaling and applying on-hit effects).

Corki is basically pre-change Miss Fortune and Twitch - lots of magic damage and AP scalings, which means a lot of early game burst potential and not a lot of lategame. You could say the same for Tristana, but Tristana has amazing range and attack speed late game. While yes, I've probably nerfed him a fair bit in terms of early game burst - I've given him physical damage and good bonus-AD scalings.

I'm open to number suggestions though. The issue I'm having is making it so that he can spam his skills at least a little bit in tandem.

What if his costs changed?

Missile Barrage - 10 Heat per second. Each subsequent cast in the next 3 seconds cost 5 more heat. Gatling Gun - 10 Heat per second, increasing to 20 Heat per second after 5 seconds.
