Vs roaches, why Liberators and not Siege tanks?

Title says it all. Why do most players I see opt for liberators over tanks vs roach/ravager armies? Shouldn't the siege tank be better since its harder to kill with medivac pickups? I just see liberators being picked off left and right from ravager biles. Your factory really isn't in use anyways with bio-lib. Plus, you should have a large medivac cloud (which was a huge problem for roach/hydra back in HoTS, and iirc it became impossible to actually trade with the bio ball since you had too low DPS to actually kill the ever regenerating army) since you're not making liberators and they have no direct anti-air, allowing you to drop more which is incredible vs the immobile roach/ravager army, and have a large amount of medivacs for your siege tanks. Plus, does the liberator really deal that much more damage for it's cost?

I'm a zerg player and I'm really curious why people don't go for tanks when I watch terran streams IE Polt.

Tanks aren't really that much better at killing roaches, and take a crazy amount of apm to pick up all the time to dodge corrosive biles. Liberators are arguably more mobile (tankivacs are mobile but too hard to use when you are also microing your bio really intensely) and have much more potential to punish a zerg, and only cost 25 gas more.

Does splitting vs the bile really take that much APM? Perhaps it does. A terran should just be able to press their medivac hotkey, press d on some location and start splitting then. Plus tankivacs seem much safer: if a R/R push comes early on, you might lose a liberator, but the tank can live forever and provide important DPS. Plus you can get such a big tankivac cloud lategame thanks to dedicated starport production and the inability for the R/R army to kill medivacs. Also, since its fairly back and forth, preserving units should be fairly important, which is what tankivacs can do.

aren't tanks theoretically better than liberators at dodging corrosive bile? with liberators you have to wait for the unsiege animation, but with tanks you can pick them up instantly and then move the medivac.

Both are pretty bad options vs early Ravager pushes, and once you hit late game Liberators are easier to produce, replace and control, are more likely to survive, are better vs common tech switches (muta, ultra) and are simply harder and scarier for zerg to attack into.

If it's early game Ravagers Roach, banshee will be better than siege tanks and libs imo

It's really time-consuming to pick up large numbers of tanks. You can't just queue it up, it doesn't work fully with more than 2-3 tanks. Hence why you do see some tanks, but only in small numbers that can still be effectively microed.

Side note: liberators are also good against ultras as the game goes on. Tanks lose utility fast.

purely theorycrafting: maybe tanks are vulnerable to a muta-switch, while liberators are useful against most zerg comps?

We see this in tourneys and on streams. A couple tanks for the helpful splash, but the bio army backbone with libs as primary support. Libs are easier to micro in larger numbers flying over the bio: They're one unit that's relatively agile moving from fight to fight, not two units depending on precise rightclicks.

A corrosive bile lands in mere second, usually on multiple locations on the battlefield. Whilst in isolation selecting a medivac, clicking booster, moving towards a siegetank, picking it up, and d click somewhere else is a pattern of half a second to a second, you are looking to do this at multiple locations at the same time, while also making sure your bio doesn't run into the instakill zones.

This is easier said then done. Splitting bio ahead of time is easy, but it also ensures you lose so much DPS in the battle that you probably lose to the Roach Ravager army head-on.

As for lategame, Roach Ravager adds Hydras, Lurkers, Vipers, Infestors. All of a sudden, Tankivac is completely inefficient whilst Liberators still have their use in their high DPS and superior zoning.



As a sidenote, I think a combination of Liberator/Siege Tank is the best, with the Liberator mobility and Siege Tanks large zoning potential.

why not both? They complement each other well on top of a ramp.

Tanks back further, so if the ravagers want to snipe the liberators they have to walk in siege fire. From what I've seen, as a Zerg's POV, this is the only time i don't go up ramps

Because tanks are underpowered right now. The damage isn't proportional to the lack of mobility they sacrifice.

Making even 1 of each costs a lot of gas though. Can't always afford it.

Liberators provide equal, if not better zoning, even if it's a fear thing. Liberators deal with common follow-up's or tech switches. Liberators are a lot more set and forget than a tank (lol). It's a lot less intense to control in a fight, splitting bio, planting mines, kiting and whatever else will simply not allow you to control tanks as well as you would like with Medivacs.
