Good reply and counterpoints. A few comments:Moves like Will-O-Wisp and Focus Blast are used because they have strategic merits: Will-O-Wisp can cripple a physical attacker, while Focus Blast can provide crucial coverage. They are used in spite of their low accuracy because their accuracy isn't so low as to be a complete gamble. Inflicting an opponent with paralysis may cause the opponent to miss a turn 25% of the time, but the primary reason people use Thunder Wave and Glare is to lower an opponent's speed, and if they are harnessing full paralysis, it's in combination with a flinch chance and maybe Serene Grace to push the odds up into reliable levels.
Speaking of flinch chances, moves like Iron Head and Scald have low chances of inflicting their secondary effect, but the effect is just that. Secondary. Unless you're Jirachi, you don't run Iron Head for the flinch chance, but rather for the damage. Scald seems to bely this with Pokemon like Toxapex, who run Scald mostly for the burn chance. However, consider that Toxapex is very likely to survive long enough to use Scald many times throughout a match, pushing the chance for an eventual burn into reliable levels. It's also worth considering that on purely defensive Pokemon, Scald is much less attractive in the presence of Will-O-Wisp, as evidenced by Galarian Corsola.
Clearly, it's impossible to eliminate all luck. Damage rolls and crits are built into the very fabric of the game, and banning everything but moves with perfect accuracy and no secondary effects would obviously be absurd. So the question is not "is there luck present?" but rather "is there value in this" which is determined on a case by case basis. The chance for full paralysis is unfortunate, but we deal with it because paralysis has competitive value because the speed drop allow for interesting strategy, like supporting slow attackers, and counterplay, like switching in an already slow Pokemon to absorb the paralysis. OHKO moves may seem like more extreme versions of Focus Blast, but they're banned because outside of highly specific scenarios like Sturdy and type immunity, there is no counterplay beyond switching in something that can deal with the OHKO user and pray the move doesn't connect. Zap Cannon is similarly unreliable, but is isn't banned because it shares the same interesting counterplay of Thunder Wave. It's just that Zap Cannon is so unreliable that almost no one bothers using it, because the reward isn't worth the risk.
In its current state, Moody isn't broken just because it's random. I have no strong feelings about Moody either way, but the most of the people arguing for its re-ban are doing so because it doesn't have interesting counterplay. Glaile's gameplan revolves around spamming Protect, Substitute, and Disable in order to stall for favorable boosts. Counterplay obviously does exist, but the question of whether or not that counterplay is too restrictive or interesting is up for debate, and most people here seem to be of the opinion that it is. It has nothing to do with jealousy (really not sure where you pulled that from).
I've come to respect you in recent times, so please don't take this explanation, nor my continued confusion over why you even care about Smogon's decisions, as demeaning. I just want to explain why the situation is more complicated than you're suggesting.
They can easily use Protect to block your Taunt, then shut it down with Disable.
I would also argue that Moody has competitive merit like your explanation for Focus Blast etc, and it’s basically the only way to make Glalie and Octillery competitive. So from that stand point, it has competitive merit if you want to use those Pokémon.
It’s sounding more and more like Substitute is the actual problem, not just for Moody abuse, but also for Nasty Plot/Dragon Dance set up sleepers like Hydreigon who abuse Substitute as well. Rather than banning Hydreigon in the near future, you could simply ban Substitute and take care of two birds with one stone. Same with the call to ban G-Darmanitan. Seems you could just ban Gorilla Tactics instead of the entire Pokémon. But I’m going on a tangent now. I like to have as many Pokémon available for the meta as possible. Like when Snow Cloak and Sand Veil we’re banned in a previous meta it made Glaceon unusable as well, which was just silly. I think we should look long and hard before rushing into banning whatever the trending annoying set of the week happens to be.
And as for the argument of “why should we be forced to include counter play Moody in every team”... well that argument is a slippery slip because we already have to be forced to include counter play for Stealth Rock in every game, and that’s just one of many similar examples (think Landorus in previous gens too). I don’t see the problem in forcing people to think about multiple counterplays when constructing a team. Your team is never going to have the perfect answer to every possible strategy. That’s just Pokémon for you. You build a solid team that handles the most common threats and hope for the best.
