Well, you talked about as a counter to bio. Every zerg will tell you that roaches are less cost efficient. They are also supply inefficient, so you have to make more ovies = even more cost inefficient.
Have you ever seen a pro zerg counter bio with roaches?
The only time roaches > zerglings vs. bio is if you are incredibly larvae capped (but you probably lost anyway in that case).
and banelings used only to counter workers... I'm almost convinced now you've never even PLAYED this game, let alone watched some actually good players before making incredibly bad arguments.
