At least in ZvT, not sure about ZvP
Just so people don’t automatically assume I am super biased I main Toss and off race zerg.
First video is of Vibe analyzing Serral starting to his this “new” lurker viper comp after the patch and how effective it is, in this case against bio tank:
And here is a video today of Serral against Inno sky/mech (BC, liberator, thor, tank, Viking, BF hellion)
He absolutely crushes it. He even makes some very uncharacteristic mistakes like letting a multiple hellion runbys torch workers including one that gets 27 in one go. And he still crushes inno. It could have honestly been a lot worse.
So the build is pretty simple. Get hydra lurker and a TON of Vipers. Get infestors if he goes BCs. BCs? Just abduct (or neural). If he gets Thors? Abduct again. Serral didn’t even bother to split his Vipers and just crushed any thors that walked up. Vikings? Parasitic bomb. Liberators? Parasitic bomb or abduct, your choice.
So the answer is tanks right? Nope. First of all, Good luck exploiting that 3 range advantage over lurkers. Tough to get vision when vipers rule the skies. Already tough to micro tanks but even tougher when you are trying to move forward while staying out of range. Couple of times inno lost tanks because he crept 1 or 2 too far. Not to mention, how are you going to stop the abducts? And even if you manage to do it perfectly, the zerg player can unburrow his lurkers and move back before your tanks even complete siege. And the best part? Its not like an immobile broodlord army. The mech comp is immobile, especially the Thors. So if he can zone out your lurkers and vipers you just attack somewhere else!
Lowko said that maybe ghost would have tipped the balance. I don’t think so. Especially if Serral tried to split his Viper but either way, the lurkers are going to be too good at zoning because they outrange the ghosts.
Maybe its not unbeatable but this isn’t just theorycrafting. The replays show some good evidence that it hard counter most and maybe even all terran compositions. At the very least, I think people in the forums (including me) dismissed any complaining about how much stronger lurkers are with +1 range and just assumed siege tanks would easily counter them. But in the right hands with vipers supporting its pretty scary.
Edit: Oh and another thing… be ready to burn a lot of scans unless you want to invest resources/supply in ravens… that can also be abducted.
