I believe most people will still want another redfor aircraft capable of BVR. The blue aircrafts in DCS are just way more modern than the red aircrafts. It is really a struggle to fight in MP using red aircraft. Also, a modern multirole aircraft will have more functionality than an old aircraft, it is definitely more fun to fly a modern aircraft in the long run. Thus, please consider the J-10, or other modernized aircraft like J-8F.
