Again, don't really care about freeze.
But again, I'm strongly in favor of changing paralysis to decay 15% when fully paralyzed.
Thunder Wave and co. are far, far better than other status effects. Going to for now ignore how the argument of "paralysis is better than other status ingame so should be better here too" doesn't really make any sense and is inconsistent with other things we've done mechanics/policy wise in ASB, but regardless of that paralysis is leagues above other statuses -- to the point where it's very possible to nerf but still leave it as stronger than the others should people choose to do so.
Firstly, 25% PAR is much easier to inflict than sleep and freeze, but also on average will cause Pokemon to miss out on about as much/more actions than the other two. I did the calculations out yesterday, and assuming a Pokemon has 25% PAR before it acts a1 (ie, hit with Thunder Wave before it acts), on average it will be fully paralyzed ~1.55 times before the paralysis fully decays. Likewise (and perhaps slightly more realistically), if a Pokemon has 25% PAR before it acts a2, on average it will be fully paralyzed ~1.4 times before the paralysis fully decays. Even just at a surface level, this is annoying because sleep on average puts a Pokemon out of commission for 1.33 actions, and freeze 1.5 actions. But then, most sleep moves are unreliable, and freeze isn't even something you can really choose to inflict on the opponent. This of course also doesn't even consider the fact that paralysis also has another completely different (and powerful) effect.
But, like I mentioned in my original post, it also doesn't consider the fact that with paralysis you can't be certain when it's going to happen. While losing an action or two to sleep is annoying, the moment your Pokemon is put to sleep you know which actions they will be asleep for (and if you're constructing orders after this happens, you can just use Sleep Talk). However, someone ordering with a paralyzed Pokemon doesn't have this luxury. You have access to chance subs, and that's it. This isn't enough though, because it's very likely you'll lose an action to paralysis, and even with chance subs you probably won't be able to execute anything good. The uncertainty of paralysis hardly matters to the one that inflicted the status, but it's a huge detriment to the other player. I'm not going to write an essay on why this uncertainty is way worse for the statused Pokemon, but if someone really wants to debate me on this, let's go.
So, not only does 25% PAR put Pokemon out of commission on average as long as the other two statuses, but the way it does so is also way more annoying. And AGAIN, this is not even the only thing paralysis does. And AGAIN, it's way way way way way easier to inflict.
Changing the decay when fully paralyzed to 10% would make it so that, on average, a Pokemon will lose 1.25 actions to paralysis when inflicted with 25% PAR before they act a1 (or 1.15 if it's before they act a2). Changing the decay when fully paralyzed to 15% would make it so that, on average, a Pokemon will lose 1.08 actions to paralysis when inflicted with 25% PAR before they act a2 (or 0.99 if it's before they act a3). Because it's so likely that with 15% that a Pokemon will only lose 1 action to 25% PAR, this is why I'd prefer that. If people would rather do 10%, that's at least progress. Either way, paralysis is still better than sleep and freeze due to again, the uncertainty of it, how easy it is to inflict, and how it still has another effect.
I have to go but will probably write more on this later.
EDIT: Very quickly going to address TSRD's post. The argument of "I just don't want to see asb following the same road of banning and clauses and altering that so many want done there" doesn't make sense to me because... this isn't a ban? Just a slight mechanical nerf. Regardless, this isn't like ingame where the mechanics are given to us. It's not like there was a huge amount of thought put into the balance and design of ASB paralysis, but just because it wasn't constructed in a balanced way doesn't mean we can't tweak it to make it slightly less ridiculous. :<
