not to critique your post, which i find thoughtful and well written, i have to point out something you forgot when discussing misconception #2, flight.
Although all of the powers you have listed do have -fly, You left out the single biggest -fly power in the game, Air superiority. Air superiority is a fast recharging melee attack with a /very/ high chance for knockdown and a -fly component to it, and is available to all AT's through the flight pool. In fact, i know quite a few other people (Brutes mostly, becuase of the speed, knockdown, and decent damage fit into an attack chain quite well) who take this power without actually taking flight for their travel power. Personally, I've not had too much trouble with the power myself becuase the only toons i have with flight are ranged toons, and I keep out of melee range whenever possible. However, even then, i once took Air superiority on my corrupter, and found it incredibly useful for escaping from flying oponents who were beating me senseless, I'd simply flight right at them, hit them with Air superiority, and fly away giggling and laughing.
But on the whole, great post
