Guys I need help . My Zerg vs Terran is pretty solid vs Marine Tank (I play a ling/infestor style with the occasional incorporation of speedroaches) however last night i played 2 practice games with DaNoSauR who went mech both games.

That is the link to the second game (First game was Antiga close spawns which killed me regardless)

Basically I scout him going mech and switch to +1 ranged and +2 carapace over 2-2 (melee-carapace). I pump out a few roaches while mass expanding and fast teching to broods. From there the game becomes a bit weird but DaNo plays a very passive style of mech (no hellion runbies) and I feel like if a player incorporated that into this play, I would just die . (I do make spines at some bases and leave roaches there in case but I'm still worried. Anyways guys it would be so very much appreciated if you could take a look and tell me what I'm doing wrong or right and what things I could incorporate into my play.

Thanks so much
