How soon do u get overseer usually? they have new skill as contaminate and spawn changeling which I think it will be very interesting to be use

banelings could deal a truckload of damage if u have the micro...
they explode when the die so its important to place them at the right position through moving and not attacking...

if they go for MM, just infestor fungal growth em over n over again...

Hi, care to share a stretegy on micro-ing Banelings ?  Wat i usually do is i keep a few banelings hidden away, and when they attack, my banelings steamroll them from behind... ( thats for early game )

But if i have to assault them head-on, i need ALOT of banelings to actually get pass those pesky MM builds. Kinda wasting there. 
note that this is before i got Burrow. I usually get rolled before i get Lair + Burrow researched. =.="

With corrupters, the static defense gets nullified long enough to make the harass effective, accomplishing what the Terran could otherwise almost ignore with proper turret placement.

If the Terran didn't scout, the Corrupters still aren't wasted, as they can take a couple pot shots at other production buildings in the mean time, then do their proper job on a return trip later in the game. And hey, if there aren't turrets in the first round of harass, then your 5-6 mutas are still having a hey-day in the mineral line.

got some question here...

about a strat in ZvT, "13 Pool 18 Roach into Air"...

if u see carefully, it says:
as i know, the spell to disable buildings is on overseer and not corrupters...
and corrupters only can attack air units...so how does it perform "pot shots" at other production buildings?
and disable turrets? 

previously, the spell is from corruptors, patch changed it to overseers

I only use overseer to scout/contaminate. Corrupted is one of my favorite unit since a good corruptor/broodlord army is nearly unbeatable unless they mass vikings/pheonix.
