That cutscene at the end of Ego Draconis where Damian's flying fortesses take out Champion Harbour? I'd like to see something like that playable - you as a dragon need to defend some place from an attack by Flying Fortresses and enemy air units.
You don't really NEED to take out the towers in FF missions because they can't threaten you on the ground. The next game should have anti-ground towers that a dragon must take care of before assuming human shape.
I'd also like to see missions where the Dragon can lend support to a ground army, whether by taking out anti-GROUND towers or destroying gates and barricades, or taking out tough airborne opponents who would threaten ground troops.
A dragon mission fighting against a large "capital ship" zeppelin would also be a blast.
What I'm saying is that the dragon gameplay needs some spicing up. It's mostly used just for transport in the Ego Draconis part.
This are nice suggestions ! Stabbey, you bring many nice suggestions for the Dragon part in one post together.
2. More frequent autosaves with less of a delay
O no, I don't like the "auto saves" at all! Maybe it's better to make the "option" to set off or on all auto saves. I never used any of the auto saves.
I like to see :
* give my Creature a name (someone suggested this already, nice!)
* Special for "slow players"

: a skill to
slow down the Time, so all the enemies are walking and moving slower ! Some of the battles are SO fast I haven't the time to realize what really happened during the battle

! For example the fight with Amdusias, the fight with Razakel & Laiken,
Sooo fast, brrr ... nasty
No serious : I think it will be great to have such a skill so I have even more FUN and PLEASURE during the fights ... It will be even great to see how I or the enemy is giving the finishing blow in (a kind of)
slow motion 
!!
