We cannot make Cloud Rider cost 2 Action Points because that would mean that two Cloud Riders could move 6 hexes per turn! What you said is a good idea but cannot be done the way things are setup right now. Assault Team is a real problem because it's difficult to make it not obsolete. Maybe Cloud Rider could be something non-movement related? I don't know..
Actually, I got a crazy idea. XD I still like YoungSot's idea, but if you don't want to make Assault Team too useless:
Cloud Rider:
"'Move' action now costs only 1 Action Point - Gain +1XP when using 'Assault Team'."
The experience gain can change, but this way, you are given MORE rewards for moving as a team with your allies than by moving alone. Sort of like a flock of birds; the more there are in a group, the stronger the flight formation/team. Birds that peel off can do whatever they want of course, but they won't be able to reap the benefit of moving as efficiently (aerodynamics) or as effectively (being protected by teammates).
Downdraft is identical to Evasion, yes?
I meant to state, "Cancel the stance", so that the person doing the charge/aggressive charge not only won't attack, but ALSO won't move...
That is pretty similar to Evasion now that I think about it.
I love Overcast and I think it's perfect but I'm not a big fan of the name. Overcast? That's a type of weather, right? Or is there some other meaning? I think that the concept of controlling vast areas from above fits like a glove. But the name.. I don't know. Do you have something else?
EDIT: Ah, I see you followed the theme we have in the skill tree. That explains it then. 
We could call it 'Fog of War' instead and tie the theme of a oncoming/ominous fog lurking in the distance capturing territory and whatnot, but I had a few other names if Overcast doesn't suit your tastes. ^^;;; I personally think that the simple ability of being able to capture hexes from a distance should be a mechanic in the game somewhere, and Air seems to be a good tree that could use the diversity.
Squall (Squall Line)?
Whirlwind
Wind Shear
Tempest
Looming Clouds (Looming Horizon)
etc. (any of the previous names that were mentioned in this thread)
too bad about invisibility being too much work. It's a really fun idea.
Another random idea:
Airborne/Hovering/Flight/Whatever:
Costs 1 AP to start flying. While flying you are not affected by anything that targets the hex you are in, but you are limited to move actions until you choose to spend 1 AP to land.
The idea is that you're flying, and thus actually one hex above the normal hex you appear in. As is it's probably too powerful to be a low level skill, perhaps it could substitute for Cloud Rider (if we're trying to change it)?
This sounds similar to Darkness' Stealth ability as well as Aether's "
Phase Shifter" Tier 3 skill. The only issue that I can see with this is that Air elements can then theoretically all 'lift off' and be immune to battles until necessary; almost like a permanent immortality that can't be removed unless the Air elemental lands. It might make them too overly 'fight or flight'. XD
