Anyway, so picture your schoolwork as a tense PvZ, knowing you have to get the most out of every one of your units to survive.
You harass a little early on, and you get a drone and a couple lings with a zealot. Then you kill off his overlord with your dragoon before it can see the robo, nice. Now your sair is out and its ontime and you pick off an ovie and head home, sticking your tongue out at the scourge. Now the reavers are out, and you harass pretty well, but he's expanding. Bit of a stalemate, gotta take some more bases. Okay, time to harass again and...
Oh, shit! A flock of muta! A gaggle of scourge! Run! Ohhhh Shhhiiiitttttttt!!! HE'S GOT A QUEEN!!!!! NO!!!!! WHY DID I PLAY ON ANDROMEDA? I'LL NEVER GET INTO COLLEGE NOWWWWWWWWW!!!!!!
*ahem*Or you could, you know, smoke less weed. Your call.
Then you've got the corsairs, mathematics. After all, we all know that 1 sair + 2 scourge = oh shit. You've gotta use these guys to not only scout his tech and harass overlords, but to protect your...
Shuttles. Or anatomy, if you're still with me on this whole SC/RL analog here, because we all know that when you're examining anatomy with a partner you're flying high nomsain.
And that leaves us with the contents of that shuttle: the Reavers. Oh yes, your biology with lab, in school terms. Cause we all know science is infinitely more fun when you're blowing shit up. Awww yeee.
