Now the flying mechanic. There is two main roles to air units: bombing and air superiority. We can aldo divide bombing in strategic bombing, destroying enemy facilities and other strategic target, like roads, and tatical bombing, which aims to desorganize and demoralize the enemy troops. Air superiority is the role of keep the skies under your control, so it is only relevant if bombing is relevant.
Keeping in mind this concepts which flavor of units would do each job. The bombing job would be done by flying machines like Zeppelins and Baloons and the air superiority job would be done by flying creatures, like pegasi and gryphons. The problem is that the job of the second group is pretty dull, but here the flavor comes in our help, as the gryphons, drakes and pegasi can enter in melee with ground and sea units. So the now the roles of the two groups of flying units are:
1) Bombers
Flavor: Air Galley, Sky Manta, Cloud Fortess, War Baloon, etc.
Traits:
Flying: Can go through impassable terrain and ground enemy troops.
Crew configuration: Like the ships in FfH 2 0.16
Tatical Bombing: Inflicts a small collateral damage to enemy units in the same square he is, and gives them the Desorganized promotion (-20% combat, there is a Disorganized II, when a second tatical bombardment happens in the same turn, wich gives -15%, to a total of -35%, but then subsequent bombing causes only damage) until the beggining of your next turn. Elite troops doesn't get this promotion, but are damaged.
Strategic Bombing: Only Lv4 bombers have acess. Can destroy improvments and buildings in the square. The chance can be modified by promotions.
Supply dependent: Bombers works like in the vanilla, rise from a base, a city or a fortess, hit the target and then return to base. The fighters don't have this limit. It's course cannot go through any square that have a Air Superiority unit, and if there is one in the target the Bomber nust fight it before the bombing.
2) Fighters
Flavor: Pegasi Knight, Tamed Gryphon, Drake Rider, Gyrocopter
Traits:
Flying: Can go through impassable terrain and ground enemy troops. Have a big chance of fleeing when the combat goes bad.
Skirmish: Can melee attack ground troops in the square it is. This attack ignores any improvment or building defense bonus, except when these structures say that it affect Skirmishers.
Air Superiority: When any enemy flying unit enters the same square it automatically fights it, and +40% against Flying units.
High Mobility: Only units with the High Mobility promotion can escape from combat with a High Mobilty unit.
How we build them? The living creatures need a stable and a Eyrie resource. The mechanichal ones need Siege Workshop.
Each civilization should have acess only to a couple of flying units. Some more concrete unit sugestions:
1) Bombers:
Sky Manta - Nest Elite lv4 Bomber Beast - Living Bomber not dependent of bases - Must have a Song button, like the lanun hero, that starts a Whale Song.
Cloud Fortress - Relic Elite lv 4 Bomber - See Flying Fortress above.
War Ballon - Bomber lv3- Can do Tatical Bombing.
Air Galley - Bomber lv4 - Can do Strategic and Tatical Bombing.
2) Fighters:
Pegasi Knight - Good lv 3 Fighter - Has acess to Air Slayer promotion.
Tamed Gryphon - Beast lv 3 Fighter - Fastest Fighter.
Drake Rider - Evil lv 3 Fighter - Has a bonus when skirmishing.
What are your opinions about these suggestions?
