I'm just a little curious about the lack of nonlinear nydus play that we see at the highest level. By that I mean, we don't really see any use of the nydus worm outside of early timing attacks against Terran.
vod(1:25:40): http://www.twitch.tv/gsl/v/40046864
Game 3 in Curious vs Byun, Curious goes for a nydus timing(allin?). As per usual, the Terran surrounds the nydus with his workers and units and the Zerg poops out a bunch of queens followed by other units. Curious gets good damage done initially but b/c of a little miss-micro, Byun holds solidly.
The idea is basically a non-committal Nydus timing. Because Terran always seems to surround the worm with SCV's what if you just committed 4 banelings to the attack. I say 4 b/c, watching the vod, Curious is able to get out 4 queens(the 4th came out at the same time as the transfuse went down) before transfusing. So it's safe to say that you'd be able to get 4 banes out most of the time. Looking at the vod again, Curious poops out banelings from the worm after the queens come out and he kills ~10 SCV's with those initial banelings. This was after Byun started to pull the SCV's away after realizing the worm was successfully established. I think it's fairly safe to say that 4 banes would get 10-15 SCV's most of the time.
Cost breakdown:
Zerg: 4 banes + nydus network + worm = 200/100 + 200(+drone)/200 + 100/100 = 500/400
Terran: 20 - 30 seconds lost mining time + (10 - 15 SCV's) = ~(200 - 300) + (500 - 750) = 700/0 - 1050/0
remark: I exclude the baneling nest from the cost b/c you're going to get that anyway against Terran and it seems reasonable to exclude that(I mean technically you have to make a pool and lair too lol).
So a nydus attack is a pretty big investment for zerg especially this early into the game, but Terran also takes a lot of damage. If Zerg focuses more on economy b/c he's only committing 4 banes it seems like there could be as much as a 15-20 worker difference between Terran and Zerg if this is pulled off successfully. Anyways I don't want to get any more theorycrafty than I already have.
So what do you guys think? Why isn't this viable at the top level of play? Do any willing Zergs want to try this out on ladder :D?
TL;DR Why not send out just 4 banes in a nydus timing b/c Terran always surrounds worm with SCV's?
