MathHammer, Episode 1: Termagants are better than Tactical Marines!

This is the first installment of a series of articles that use the power of math to show that some units are better than you think.  We're delving into some dangerous uncharted territory here, and I'm likely to make errors, so feel free to contradict me!

Everyone knows that you only take Termagants in units of 10 so that you can take Tervigons, right?  That's what the internet says, so it must be true.

As those of you who have been reading along know, we try and do things a little bit different here at Men With Toy Soldiers.  While I agree with the consensus that Termagants + Tervigons are possibly the best unit in the game at scoring objectives, I want to see if we can find other uses for them, and possibly even... have them kill things?
