>>Even flyers have to end their movement when they enter a square adjacent to enemy figs.>>

???

From the DC rulebook, page 11:

"A hovering charcater may move through opposing characters and blocking terrain."

The FAQ makes it clear that if a hovering character starts a turn adjacent to an enemy unit, he has to roll for break away, but if you are hovering, you can move over enemy units all you want, till you stop.

Soaring is almost completely useless. It is good for making a wall to protect friendly units from ranged attacks (range attacks have 1/2 range against soaring units, and soaring units block line of sight, so if you put a soaring figure in front of another figure, a ranged attacker needs to get really close to shoot you), but other than that, not much.

The Marvel rulebook has that line too but that is a bit out of context. Its the italics in the paragraph below..

Under movement there is Since they interact with non flying characters af they were on the ground, the would have to stop when coming adjacent to an enemy character. BUT, if they succeed on a breakaway roll, they can move THROUGH the opposing figure ... which is not the case for a grounded figure.
