Feedback: Minion Kills, Multi Kill

I'm not sure where to post this. If there is a more appropriate location let me know.

I'm leaving some feedback below.

All Minion Kill-Extra Gold If you kill all the minions in a wave, get extra gold for killing the whole wave.

Extra Health Regen For Multi Kills If you get a multi kill receive extra health regen for a few seconds. Deteriorating stacking for additional multi kills? Increasing stacking for additional multi kills?
