Not regarding to the complaint of the tech tree being to long or saving RPs, the Mig-fighter line is the only line where you have to research 3 consecutive Tier VIIIs for Tier IX.
From my perspective, stacking 9-12 and 9-13 is reasonable, with precedent such as J-11 and J-11A(same plane model with extra RVV-AE and MAWS), JAS39A and JAS39C(capability of carrying FOX3), Barak II and Sufa(different model and weapon but both F-16s). Mig-29 9-12 and 9-13 are:
Both early Mig-29s.
Same engine but slightly different FM.
Similar in Weapons(Same R-27s but way better R-73s for 9-13).
Repeated method and experience of playing.
Definitely something that could be considered given that the reason of implementation behind MiG-29 (9-12) was the removal of R-73 from the airframe, I don’t think it’s fair for the player’s economics to extend the grind even more because of a different infra-red missiles. Hopefully to be considered. @efetenekeci, as I’ve mentioned, MiG-29 (9-12) exist for that reason, I doubt that it’s going any lower in battle rating outside of an decompression.
I guess Gaijin will make this change in the next major tech tree adjustment but not right now.😮💨
MiG lovers deserve better grinding experience for the Final MiG Fighter.
