Hypothetically: What if Koggy's Ult worked like Corki's Q?

So instead of a delayed AoE akin to Brand's flame pillar, it's instead a missile that travels to the target location and then explodes. The missile speed could increase with rank a bit to keep its delay before hitting at maximum range more or less the same. That would make it a little more reliable against closer foes with the downside that abilities like Windwall would be able to block it. It would also improve the readability of the attack a little more so opponents can tell where it's coming from and where it's headed.

That, and I think making a big artillery round that sails through the air in a ballistic arc and then explodes would look a lot cooler than the thing just dropping straight out of the sky.
