a grounded connection between a unit and the battlemap surface - no matter if this connection is visible or not.
the moving of flying creatures will also be kinda tricky since it is really hard to make flying stop-and-go animations.
there issomething that is really impossible with the M2TW engine: creating flying units that can't stand still in the
air like the fell beast. eagles for example always have to fly. they can't stop in the air - they always have to land
somewhere to stop or they have to fly in circles and forth and back. but fell beast flying and moving like in the movies
should be possible. problem here is the fact that those flying units would not be able to fly over other things like trees
or buildings without getting stuck somewhere. even to let them fly over other units would be hard. but maybe someday
anyone will find a way to lift units a certain distance from the ground.
what i ask myself here is how these flying unit should do an attack on enemy units. dragons could use the greek flame
throwing ability from kingdoms crusades. or maybe archers on they back. but this would be kinda weird for fellbeasts.
in the movies and the books they only were used for transportation i think. they never really fought on their own, or
am i wrong here?
the other issue would be how to fight against such flying units. catapults and ballistas would have no big chance to hit them.
archers would be the only way to fight them. but archer suck at firing at fast moving units - now imagine they have
to go for a fast flying unit. really not easy.
but someone should try it out. i think it is definitely worth a try.
