don't see this happening either. Too little actual gain for too much work. While you can say the systems are still there, that doesn't mean they wouldn't need a bunch of work to be implemented into classic. For, unblockable arrow and a teleport. Would be a waste to me.
Don't know if this idea if from Older classic versions, but please stop suggesting things from older games. It's not that the ideas could be bad, it's that the staff already knows about pretty much all of them, and if they wanted them to be implemented they would have been.
