With the range of roaches being increased my factory play has been hit relatively hard. Before I used to go double factory hellion/thor and one rax for marauder. I made a post calling this an unbeatable strat for zerg players… and indeed it was. Every single unit they could throw at it would die. But with roach range being what it is now, roaches actual;y do some damage to this build.
What I’ve been doing more often now is one factory/one rax expand with thor/hellion/marauder defending. Luckily this build still can defend any sort of push. I usually throw up a rax once my expansion is up and pump out marines. I mean I seriously need more minerals. This of course makes me vulnerable to banelings.
So I get siege tech and pump out some tanks. Once I get 4x gas I get out a second factory with constant thor/tank production. Sometime I’ll make a pre-igniter hellion if my gas is low.
So my composition looks like: marine/marauder/hellion/tank/thor. Also possible that I’ll get a raven or two out for seeker missiles if the game goes on long enough. This build doesn’t ‘win’ games for me but it does make roaches far less of a pain.
Zerg have REALLY been trying a lot of new stuff as of late. One tactic that ‘got me’ was one-base infestor. It’s kind of weird and you’re really sitting here massing thors thinking he’s one-basing mutalisks. But then the infested terrans show up and you go…. odd.
The most common thing and most destructive to my old build is mass economy bulids. Mass economy was pretty uncommon before because barracks-first builds forced zerg to always put up spawning pools first so they can protect their expansions. But now that they early expand first every time mass economy is far more common. Basically if you put no pressure on a zerg player can get out his second expansion by the time you lay down a factory. The mass economy build’s main focus is getting out ultralisks or brood lords. So they’re just stalling for time until they can get them out. Once they insta-hatch stupid amounts of either of these units you go, OH…. crap.
Ultralisks are far deadlier than the broodlord option simply because the ultralisks are going to cleave through your mech. Having more tanks, marauders and marines around definitely helps with the ultralisks. Thors just crumble. Drop ships as well are huge in any thor vs. ultralisk scenario. A lot of times I”ll have thors up front and just load them into medivacs when they’re health is orange. I’ll fly them away drop them off and repair them. It gives thors a fighting chance against an army so heavily ultralisk.
The shitty thing is you need thors. If you build too many marauders/tanks he’ll just hatch some mutalisks out. So until you can stim marauder drop his spire you need them around to deal with the threat.
It’s a very uneven battle. You have to have units available to deal with every possible threat he can throw at you and he can mass any single unit to wipe out any single type of unit. Good news is most zerg still haven’t seemed to figure out that they can fast expand so most TvZ is still pretty imbalanced towards terrans.
