I'm quiet excited for this game, it looks amazing!
However having years of starcraft, I'm used to real time strategy, after playing a few games I'm addicted to playing as the dragon too, however while in dragon form there's no command card.
I could imagine that being an issue while in dragon mode but I also noticed that some of the hotkeys from what you may expect, have allready been changed for the camera movement (WASD) So I was wondering what the harm was in allowing command cards to show while in dragon mode to continue having your army buff eachother and better follow your orders while having fun burning down the village 2 feet over!
On a very similar note, I've thought about control groups, again having played starcraft I find them very useful, and as they are used in dragon commander, they aren't in dragon mode, simple hotkey useage (1-9) is allready taken up, shift+1, or control+1 add or set control groups, while in dragon form maybe shift+1 could select the units in some way? Or control and shift, and 1? It would take less time to switch between dragon and overview mode, and hurt the battle a lot less by doing so. Otherwise you have to leave the battle, macro up, wait for the dragon to be readied again, then spawn back in.
