Yeah, this'll help you play meep DAMN GOOD. Just hold on tight to your spaghetti, it's gonna be a wild ride.

Hotkey your main meepo to 1, all of em but the main meepo to 2, and hotkey all meepos, including the main meepo, into 3.

If you want to try, you can split farm with your secondary meepos, put two meepos on 4 and two on 5, keep an eye on their hp bars at the top left to see when they've cleared a wave/camp and remeber to watch the minimap.
