Exactly this.
It's so fucking annoying to only see Main Gun and Engine crits all the time and nothing really new.
In the beta it was hilariously annoying because those crits happened for nearly every vehicle impact. You could easily lose a tank because you got a chain of Gunner Injured/Driver Insured/Crew Shocked over and over without being able to retaliate. It made tank battles extremely RNG based to an absurd degree, and was quickly removed from the game.
