And when will we have Collision Detection and Mob Behaviour back?

[Vesperia]

After watching Jurassic park, they should have done this with Raptors:

You attack a raptor that you believe doesn't suspect you, and when you attack, two more come at you from the sides and you find yourself being triple-teamed. :O

That would actually be pretty cool to see, but it would start to suck after a while since it'd be too hard to beat them :P

That would be cool, and they should be able to open doors and speak to eachother. Rather than aggroing on sight or smell, they track your footprints and actively seek you out. And when you die they eat your corpse.
