I'm a bit late, but dropping my idea anyway.
Now that we're talking about different tiers, why not base mid-air control on that?
The Tank, the heavier tier, could not have any mid-air control whatsoever, the Normal tier could have the mid-air control that we have now, left and right, and slow, and the Fast tier could have little thrusters that let you, not very fast so it doesn't ruin the immersion, turn mid-air in all directions.
Just and idea though.
I'm Spanish god dammit sorry for my effing grammar jeez.
