So i've seen alot of terrans recently going mass ravens and wow that strat is just ridiculous. I mean Terrans have always been pretty good with marine siege tank builds, but talk about some versatility when it comes to being able to drop 30 turrets and run away losing no units in the process only to come back in a minute and do it again. Oh you have ground units trying to attack air? How bout a multiple HSM to ruin your day. Shockingly effective and ridiculously infuriating to face I was just wondering if anyone had an effective way to combat fast raven play?

Huh. I would like to see a replay of someone doing that. Sounds interesting...

Huh, someone tried to do that but they only had like 10-15 ravens in a 3v3, my MMM+Vikings ruined his plans.  It doesn't work very well TVT if the other terran has the sense to build stim marines or vikings..

I went Zerg in Steppes of War against a Terran who added mass ravens (mass as in between 6-8 of them) to his MMT balls. It's tough as hell to get into the typical zvt contain-and-out-harvest strategy against. All those turrets, HSMs, and point defense drones tear mutas and corrupters to shreds.

I have a friend who was on a mass ravens kick for a while. It was always funny to see him do in a team game when he'd basically roll in a base, drop all his turrets and then roll out. The base was basically gone just from that.

1.Replay
2.If you let him go mass ravens then shame on you, you should've just killed him
3.Replay
4.If you're toss, go ht's, if you're zerg - go speedlings 
5.REPLAY

Mass Ravens have been covered by a few casters, i think either HD or Husky covered one or two.
