Is it a good choice in zerg vs zerg matches to surround the mineral line with buildings, so that mass zerlings cannot enter ? listening to your opinions
that seems like a good idea but then you might not be able to defend your mineral-line with hydras against air units like mutas
I feel like it you block you mineral line, then you should make sure to either have spore crawlers or have your own muts for AA, or atleast have the option open.
It's only a good idea if you are planning to tech up to fast mutas. A better idea is to get quick roaches and make a roach wall at your ramp using hold postion so you have some units. Avoid building spine crawlers and spore crawlers because they only have one use, and are probably only used for that one time. Only times i use spines are when I FE and my army is small.
