So it's legitimate to abuse RNG to steal free turns when your goal isn't to steal the free turns. Riiiiight.Last time I checked, coins and d4's were completely different things.
Paralysis spreading is a legitimate tactic for lowering a speedy opponent's speed; the 25% chance of a free turn is a bonus for the T-Wave user. Ground types and Electric types are immune and plentiful enough that either can easily be put on a team without being dead weight.
Swagger more or less forces a 50-50 on an opponent with little (if any) counterplay involved when Prankster is added to the equation. All "counters", barring everyone switching to Stall (which is overcentralizing just to counter ONE playstyle), are sub-optimal or just plain stupid to use in OU.
It doesn't matter that it's on a d4 or not, free turns gained purely through RNG are free turns, and the fact that Paralysis does not go away if you switch or wait it out evens out the lower per-turn percentage.
I was simply explaining why choosing to globally ban Swagger outright is a terrible idea. I do recognize that there is a problem with absurdly fast status spreading combined with ways to easily abuse the free turns gained by it. But banning the single move changes nothing about the problem and creates a terrible precedent moving forward; Thunder Wave was just an example that draws parallels.
