If I buy a sandwich and try to eat it, but due to whatever complication may arise my body is paralyzed and won't move, the sandwich isn't gone the next second (unless a THF happens to be around maybe, but not as a rule). Yes, it is avoidable by simply not using it, but losing an item due to paralysis makes absolutely no sense whatsoever and never did. It was always a bother and sometimes it isn't easy to avoid either. You don't always have the luxury of realizing your paralyze status and calmly decide whether to use the item or not. It happened to me a few times I tried to use a temporary item inside Abyssea, but that second I was hit by a paralyze move and lost it. That stuff is nearly impossible to avoid, now imagine that happen with a primeval brew.
I honestly don't get why people wouldn't want this changed. Do you think it makes sense? Is it fun to lose items? Or have you never lost an item to paralyze, which I find hard to believe? Or do you think it makes the game more challenging, which I don't really agree with?
In my opinion it's just annoying and I don't see why it shouldn't be changed. Right now, the paralyze effect kicks in after the item has been used, but before applying the effect, same goes for JAs, which accounts for loss of the item and used recast. But for some reason, it doesn't for spells, which I find kind of confusing. Maybe it has something to do with the cast timer, but then again items also have one. Guess spells are just handled differently, but that means it could be applied to items and JAs as well, although I'm not sure if I want it to change for JAs as well, otherwise they wouldn't have much of a downside for being paralyzed. Maybe just introduce a general 3s delay if a move gets paralyzed? For all I care, that could also be applied to WSs, I don't see why they've been excluded from the paralysis effect in the first place.
