Yes. They are OP when you look at their low reinforcement cost and how cheap they are to buy, especially if you see how many abilities they have. Typical Soviet stuff - was supposed to me bad, got buffed but the low price remained.
Low price remained after buffs?
Ce's where 200mp for years. Ce's rifles became more consistant and the demo got nerfed just as their mines got with the 2 model cap.
The price drop to 170 is fully justified. Now they are cost effective nothing more nothing less.
They are a 4 man squad facing factions designed to fight 5 or 6 men squads with better long range inf and actual nades and ai upgrades. There are the reasons for them justly being cheap and cheap to reinforce. Soviets bleeding like crazy hassent changed much.
