The upcoming Kog buffs WILL improve his mid game

His late game, too, sure. But it'll have the largest impact early to mid, which is exactly where Kog needs his power padded if he's going to do the Juggermaw thing. After all, if a champ's damage isn't kicking in by the time team fights are ramping up then why on earth would you want to build a team around them?

So.

Good going there, Riot. I'm not being sarcastic.

However

And there's always a however.

This is probably the least interesting way to improve Kog's power. This just makes him a bit more stat-check-y than he was previously, and I'm not sure if that's the best way to improve him, all things considered. If we're wanting to kick Kog's sustained damage up a notch, might I make an alternative suggestion?

Give Kog's Ult it's full powered execute back against targets below 25% HP. However, also add a new component to its debuff that triggers when Kog basic attacks the target. This could be a straight OnHit effect (if you want to be more sustained damage-y) or a single-proc per application deal (if you want to be more spellblade-y). A %Current HP effect would probably be the best way to go, since that would give Kog a pretty compelling reason to use his Ult against healthy targets. And because you can actually dodge Kog's Ult, that's quite a bit less stat-check-y than just lumping more damage onto his W.
