Not really sure if putting thoughts opinions or facts all in caps gets anywhere more then just typing them out.
Anyhow. As for what is realistic and what is not that would be rather hard to determin in a fantasy game.
Some are looking for the shock troop factor of dragons that respawn others dont want to loose real life money if they spent it. However there are also some that just wish to see something new and different to be done with dragons.
Now what all that has in it only the developers truly have the power to see or create lol. Time will tell I reckon.
Alot of good ideas floating around so far.
