Ost sniper is too micro intensive to be worth it right now.
Sov sniper isn't exactly a-move unit too you know. Snipers are micro intensive units, for both sides, unless you believe that constant keeping them in cover even when moving from A to B while protecting them with other infantry, which include flanks is a natural skill of every soviet player.
And yea, addressing OPs argument about retreating through cons-you have failed your positioning/scouting/situational awareness if you let cons get behind your sniper. There is nothing wrong with soviet one and there is nothing wrong with wehr one, survivability of these units will not ever be changed which was stated 9+ months ago by relic already, so stop trying to win by nerfs and try to win by micro if you're going to use most micro intensive units in game, many players already have proven how valuable and deadly wehr sniper can be when used and supported properly.
