The Gripen series of jets has been nerfed into oblivion since its introduction into the game. Since the introduction of the Gripen-E jet around 6 months ago, the top-tier air RB competitiveness for Sweden has been somewhat alright–not the best jet, but definitely not the worst.
However, with the upcoming dev server updates adding around ~600kg of empty weight with only a minor increase in thrust, this means that the Gripen-E (a jet already much heavier than the Gripen-A/C variants) will be absolutely incapable of holding its own in a 1v1 dogfight.
As of current, the Gripen-E struggles to dogfight Rafales, Eurofighters, and SU-30s, with it only being able to reliably kill F-15s and F-18s in a close-in engagement/energy fight. With the continued airframe and drag coefficient nerfs to the Gripen, I believe there should be many better ways to balance a plane rather than repeatedly and artificially nerfing the plane into the ground.
I hope this thread is able to gain some traction.
