1- Eh, I'm not too fond of this idea, myself. It sounds too much like WQ, and the random fainting sounds like it'd be a hassle. I mean, we still get people logging in and whining about not knowing how to move. Imagine how many people would start panicking because their character suddenly fell over. Plus, it'd probably be a pain to code into the game, anyway.
2- You can kind of already make your wolf/lion look more "masculine" or "feminine" via manes, tufts, etc. Plus, not everyone plays a lion. Some people like to make other felines, like leopards or panthers, where the males don't have manes.
3- All this has already been suggested
As of now, no one's really sure if it'll happen or not. I think the tail flicking and such is likely to happen, though that's just my personal opinion.
