Easymode in WB did 2 things: AoA limiter and autotrim.
It did weird things in vertical, as the planes wouldnt depart, but merely 'mush' out, making standing on the tail and weird vertical moves possible. It was also a much more stable gunnery platform.
It also made stickstirring rampant, as people wouldnt stall out while doing it. The day easymode was removed, 60% of the topscorers disappeared from the top20, together with 95% of the rollwarping 190s. (And a large amount of the Ki84's disappeared too, as they were quite prone to spinning).
