Time to rehash the Sleep argument here......
Was discussing this in the
1v1 room yesterday, and thought I could throw more light on what I believe to be a flawed argument from the anti-ban side...
People kept throwing this reason that if Sleep needs to be banned at all, only those with imperfect accuracy need to be banned, because theses cause RNG on the part of those sleep move users. What I find as "flawed" in this logic is that the people who were saying this seemed to be forgetting that the "accuracy of those sleep-causing moves" causes lesser loss of control in the game than the "number of sleep turns" which is inherent by using Sleep-inducing moves (however accurate they may be).
Another argument that has been, and was, thrown around was that if Sleep needs to be banned because of whatever RNG is involved in it, then moves which can miss also need to be banned because of similar reasons. Again, what I find flawed in this logic is that even if the inaccurate moves, like Hyper Beam or Head Smash did land on the opponent, your opponent on the field can be EVd to survive hits from the not-completely-accurate moves. In the case of sleep-inducing moves, the number of turns one is asleep can range anywhere from 1 to 3. During this "sleep", do note that the opponent cannot be damaged
apart from the noteworthy Sleep Talk Heracross TI mentioned in a post long time ago. And also, the opponent can put the user to sleep for many turns. This means that the Pokemon on the field needs to be ready not just for the (maximum of) 3 turns it can be put to sleep, but for many more turns, which is simply impractical to ask for. This impracticality is not posed by moves like Hyper Beam or Head Smash, because even when they land (assuming they KO), they finish the match, or they don't; their landing on the opponent does not call for overbearing bulk, because they have certain drawbacks in their usage.
I'm sure many hyenas would take this as the opportunity to pounce on me, and use this argument against Z. But, this is not a discussion about how something is banned, but something else is not. If Z-Moves are not banned now, using this a precedent, you
could get that banned at a later point in time. But, for the time being, let this be about sleep (my request, you could ignore it, as well..... /me shrug)
