I just believe for the purpose of this discussion, both sides should stop ignoring the arguments of the other sides. Lv 50 proponents, especially the sheer amount of them who don't actually play this game, really need to stop undermining the difficulty of adjusting between 100 to 50 and back for multiple gens especially the longer you've been playing this game. It's legitimately instinctive, we just "know" what lives and what doesn't, what outruns and what doesn't, and it's always difficult playing against instinct. I do not believe that ignoring that for the sake of this proposal is legitimate, or bringing it up being infraction worthy. Likewise, considering the what, 10 years, of lv 100, the burden of change is on the side advocating 50. As such, "it's not a big deal" is not a valid argument. It is not enough to say "the lv 50 swap is not a big deal, and since you cannot prove that it is, we should do it." That is both egregious and fallacious.
Now, I recognize the desire to make it easier for future Wifi players who want to use Smogon stuff. But I, in an attempt not to dismiss the argument, really don't get why that's such a huge deal. I likewise do not think that side has met its burden. The OP itself even engages in that burden of proof fallacy that is legitimately rampant through this entire thread. "There are two main counterarguments to this proposition: tradition and "simulators should remove all the hard work." To these two counterarguments, I say, "Why?" Is there really a need for us to continue the trend of Lv100 battles simply due to tradition?" is does not actually say anything. It is asking for the lv100 proponents to prove their counterarguments, when we should instead be requiring the lv50 proponents to prove their arguments.
In my opinion, we should stay with lv100. I believe this because, honestly, tradition. 5 gens of lv 100 and 1 gen of lv 50 seems clunky, awkward, and annoying to deal with for tours that require multiple generations. We should not in any way revert to lv 100 for tournaments (I believe I saw this mentioned) if the official tier is lv 50--that just establishes we have no confidence in our decision. I likewise believe that the amount of good that has been stated is a severe exaggeration on the part of the lv 50 proponents. The analyses work for lv 50 and lv 100. That's just true. The strategy behind the Pokemon do not change, and minor differences can be accounted for in the analyses if necessary. The game is not less accessible for Wifi players. Wifi players that want to play on Smogon simulators will. If they want to stay Wifi, then they will. The level difference is not going to change that. Finally, it has been shown multiple times in this thread that obtaining Level 100 Pokemon and breeding perfect Pokemon is actually incredibly easy, Rare Candies or not.
Considering what the proposal is supposed to do, and what it will actually do, I do not believe the lv 50 proponents have met their burden. While their might be some minutely positive changes, it is not worth the net harm that it causes (deviation from tradition, relearning process for many users). I believe we should stay at Level 100. The simulator has been simulating what we CAN have. It always has been. We have always played with level 100 Pokemon with perfect IVs and obscure events because it's POSSIBLE. Leveling to 100 is most definitely possible and in fact easy, and does not in any way detract from simulator philosophy. This should not affect Smogon metagames.
