That's why they gave users the EXP feature in flight controls - advanced settings, to dampen the sticks and help take away the effect you're referring to. As far as losing altitude in ludicrous mode, they talk about that in one of their videos. Basically to gain forward speed at that rate you're sacrificing upward power, with the Evo being a bit on the heavy side, it seems more noticable or amplified. It is universal with all drones, just less noticable with some. The Evo is programmed to regain any lost altitude once it slows or hovers.
