Recently I’ve spaded entire US V tier of early jets /air RB, and I could make few remarks or minor inconsistencies but F-84F sticks out like a sore thumb.
8.3 is BR when big bois come to play. It pushes you in 9.3 - early mach 2 bracket, Mig-21, F-104 Starfighter, British Lightning, you also meet really good Korea era dogfighters like Mig’s 17/19, modern stuff like Swedish Saab-105 and Italian G91, lot of AA missiles etc
Poor F-84F has no business there. It’s a bad plane that is marginally better than 7.0 F-84G variants, it loses speed rapidly, it accelerates slowly, it has 50 cals, it’s a piss poor dogfighter, all it can is drop bombs and pray nobody sees it or targets it because there’s literally nothing you can do. Really not fair or fun. If it drops in BR it would not suddenly become good or meta, just less frustrating to spade.
