Errr... you're probably mistaken there. :detective:
I agree there is a problem in current FM, as you described it.
But it really is related to AoA (and induced drag).
General rule of thumb:
Stay below 15° AoA: thrust > drag = you can accelerate.
Go beyond 15° AoA: drag > thrust.
Now, currently, there is indeed too much of an effect; this can lead to ~irrecoverable situations if you find yourself low and slow: you don't have enough altitude to trade when you try to unload (go 0g / lower AoA). As your former F-2000 pilot said, the aircraft should be more "gentle" and remain more recoverable (given that the pilot do what he needs to). :thumbup:

PS: AF447 was lost between Brazil and France because of AoA, not speed.
