Hey KnightLord reporting in. I played a game on the balance test map and I'll say it improves mechvZ. I say vs zerg because what it does is make sieges kill things faster and makes the Sky Terrab transition easier and more stable. I say vs Zerg because not many people use mech vs Toss because of abvious flaws in the style.
