yeah it was similar, it vas v mg s s then tech to t3. (I went bars + triage with 4 rifles). By the time I got my m8 out (smelled sniper spam) his stug was out. Then he built 2 more snipers, vetted them and all I did was bleed mp.
By the time you have 3 rifles out, he will only have an MG and a volk with this build- even accounting for mines, there is very little to stop a flank at this point.
Sniper heavy T1's go one of two ways; either he camps right next to his own base and tries to lure you in or he tries a standard playstyle, just with lots of snipers.
In the first instance, don't bother flanking him because if he's only 1 or 2 sectors outside his own base, you won't be able to get around him sufficiently and his short retreat path means that the best scenario you can hope for is taking a load of damage yourself, just to force him off the map for 30 seconds or so. Instead, take advantage of the fact that you will have drastically superior map control and build up your support army- an M8 to keep him in T2, then sniperspam yourself with an eventual howi to turn his infantry-centric build. It's boring but effective.
In the second instance, if he tries to expand early, then it's simply a case of being aggressive with your flanks. With a build like V MG S S S he has almost no flank-stopping capability besides mines and you will outnumber him for the entire length of the T1: when he has 2 units, you'll have 3. When he has 3 units, you'll have 4, etc (not including engineers, assuming you go for a 2e opening).
You say that you 'always' seem to misfire/miss his snipers if you go WSC first but statistically this is unlikely. You might miss your first shot, but it's not the end of the world. If nothing else, you force him to switch to a much more passive mode with his own snipers instead of just A-moving all over the map, and now your flanks have gained a lot more potency. If he's -very- good, he'll be able to keep hitting that sweet spot where he's firing at the optimum level between damage output and risk to his own snipers. But honestly, those sorts of players are few and far between, and even if that is the case, you'll be able to hurt him in other ways- like artillery.
