It makes plenty of sense - the OST Sniper is a one time 360 MP cost whereas the Soviet sniper costs 180 MP every time you drop a model on top of the 360 MP initial cost. So you ALWAYS spend more MP on Soviet Sniper unless you lose both models on their first tour of duty. When you take into account that Soviet Team has inferior stealth and often faces off against LMG greens where a single burst is enough to kill a model... well you can do the math.
When you loose a soviet sniper model , su is down 180 mp.
When you loose ost sniper, ost is down 360 mp.
I wonder which is better?
