I would add wings, but have them scale-able, so that you can have tiny wings if you want, and they wont get in the way of your camera angle. Besides, wings are quite helpful, Heres how
1. Able to get in high places.
2. Able to make dragons, but even better.
3. Able to explore your custom map in new ways.
5. Opens up a window of possibilitys, including markings for the wings.
6. more coding pactice!
7.Faster speed, Perhaps?
But heres the cons..
1. Realistic roleplays will be more scarce.
2. Wings getting in the way of camera angles and veiws.
3. People can get up in very hard to see places and do some....Bad things.
4. More sparkledogs and glittercats that we dont really need....
5. Crazy winged mate beggers flying around and harrassing everyone.
6. Trolls using wings to fly high up in the sky so you cant see em.
So, Theres pros and cons, I would say add them, it does add a whole new window to FeralHeart, and, if feralheart doesnt get something big, im afraid everyone will leave to Arokai.
