ZvZ Roach to Hydra ratio?

Hey I just recently ranked up to Diamond as Zerg, and I'm learning that the ZvZ match up has become incredibly sensitive to things such as army positioning (concaves vs convex) and the amount of Roaches to Hydralisks that a player should typically have:

If you have too many Roaches, your army won't do as much damage.

If you have too many Hydralisks, your army will do great with damage, but once the Roaches run out your Hydralisks just fall like lambs to the slaughter.

I was wondering what a good ratio (2:1, 3:1, etc) would be in general army size when using Roach Hydra in a ZvZ.

I find that more hydras actually help out more. Of course it does depend on what your opponent has, though. If he gets a lot of banelings, obviously you would want more roaches since Hydras take bonus damage. But in the Roach/Hydra vs Roach Hydra, I find maybe a 3:4 or 3:5 roach:hydra mix works out very nicely. It gives you enough taking life with way more dps than the 2:1 that people are saying. But, as I said before, it is very dependent.

hydras = roaches*roaches/25
Sounds stupid, but i use it
Cant use a consistant amount at all food supplies, so make the roaches first

Basically what Scrapbrain said, I'd also like to say that you shouldn't get hydras until you have big 200/200 armies. You don't actually need hydras at all but if you get them wait till you have a big army. Infestors are way better to get before hydras.

I wait to get hydra's after I get my third base up, if at all. I still prefer to get a mix of mostly roaches, some hydra's, and about 3-4 ultra's. I prefer roach/infestor in the midgame.

Infestors are better than hydras? In my experience, no, roach/hydra beats roach/infestor in direct confrontation, simply because his FG'd units can shoot any of yours if you engage, whereas nothing you have can outrange his units.

Once you have hydras, infestors become great because you can force engagements by FG'ing roaches and attacking with hydras (or hydra+roach for simpler micro); forcing engagements in advantageous terrain (where your hydras get a concave without being swarmed) gives you a huge advantage. And don't forget that infestors are very expensive, so a badly chosen FG can make your investment pretty worthless.

But I admit I haven't figured out the right ratio for this yet. I tend to lose pseudo-randomly and only much later realize that a small difference (engaging a little too far ahead/behind) nullified all the army composition advantages I had.


A different question: Is +2/+2 worth it if you already have +1/+1 with roach/hydra?

with the roach/hydra setup, you should try to do a timing attack where you have either an armor or attack upgrade finishing. If your armor upgrade is about to finish, then i'd say get some more roaches, if attack, get hydras. You need to start feeling out how many roaches HE has, and make sure you have just as many if not a few more.

More importantly, make sure you have a correct concave, and even bring a couple spinecrawlers withyou. Spine crawlers are great against roaches if they actually live becasuse of the extra damage to armored.

Personally I completely abandon the use of infestors in order to get burrow and burrowed movement for my roaches..that would allow for regeneration even if you get fungal-ed...As for the Roach to Hydra ratio, I usually go with a 3 to 1 mixture......2 to 1 would be nice but that would probably leave too small a roach buffer. Once hydras are reached by roaches they melt waaay to fast.

A slightly smaller 2/2 army will slaughter a 1/1 army. most macro zvz's i play, the other dude will always try for 2/2 so it ends up being a race almost

hydras scale extremely well with attack upgrades, even better than roaches do. roaches may gain double the amount of damage per upgrade but hydras attack more than twice as fast as they do

As far as Roach:Hydra ratios, it's been mentioned already, but theoretically you want the ratio of hydras to go up as the ball gets bigger. You should start out with 10+ Roaches before you add even one hydra, but by the time you get to 30 roaches, you probably want 30 hydras behind them.

The goal should always be "have enough roaches that my hydras never get hit, but have as many hydras as possible".

this is a terrible idea. first, you cannot burrow while being fungaled. second, you cannot unburrow while being fungaled. fungal is extremely strong as it does decent damage and lets you get the better angle in fights.

imo the right roach hydra mix depends on the stage of game. you want to have like 30-40 roaches before starting hydras (usually when you take your third), but once you have that roachbuffer, i usually mainly build hydras and only build roaches if my roach count decreases.

in split map situations with tons of spine crawlers i personally mainly use roaches for drops/nydus and use the hydras together with infestors between my crawlers to defend. so this is not so much about ratio, but more about how many units you think you will need to defend against counterattacks while you are rebuilding roaches after dropping.

lol hydras are bad.

Infestors are very good. They FORCE engagements, or delay them. Whatever the situation. If you have a roach/hydra army, and I have a roach/infestor army, I just need to land Fungals on clumps of your units, and pull back. Your not going to engage me with half your army, thus fungal do it's full damage. If we engage, and I'm on the losing end, I run away. You can't chase me, because Hydras are slowwwwwww. If I land 1 fungal on just 10 of ur units, that's 350 damage done. Alot more than what a Hydra going to do. Tbh, outside of mid-game ZvP, there's no reason to get hydras at all.

Upgrades are always worth it. Only time there should ever be a decision is when there are units coming to your doorstep and you need those few extra units to come out. There's a reason sniping upgrade facilities in bw was so huge.

EDIT: apparently hydras are good for late game ZvZ, that I didn't know as I never get to that part of the game. Listen to DarKForce, my ZvZ usually just ends up being 200/200 army of roach/infestor attacking and rein-forcing with more roaches for the win =\
