The only real niche for Conscripts early game is capping points and acting as roadblocks by stealing any structures near points if challenged. Even then, it's all too easy to be ousted by Sturmpioneers running up to whatever building your conscripts are hiding in, and forcing you out through sheer DPS. The utility of such an approach is even more limited by a lack of effective T2 AI options. You could go T1, but then why bother with Conscripts when that gives you access to Penals?
sorry but any type of squad can be one shotted, therefore no unit is 'intended' to survive the whole match.
Cons can be phased out once better stuff has been unlocked by sov player, that's a very low risk strat for sov.
