Some prices feel quite a bit off.
- KUB is one of the best pact AA pieces. It is currently underpriced. (One of my favourite AA to use). Currently its extremely cost effective.
- OSA is worse than tunguska, yet costs more. Yes, its wheeled, yes it shoots one tick further against helos, but overall that isnt too relevant in may cases. Sometimes i just need a good affordable AA piece, which is Tunguska.
- There is no reason to take the advanced strela car for 120 points in 27th since for 15 more points you get tunguska which is significantly better both against helos and planes.
For comparison, - here are well priced pact AA:
90 point strela, 135 point tunguska, TOr for 140 and buk for 155.
