Even though confusion is pretty damn annoying, I'd have to say that I hate attraction the most.

BTW, you missed Sleep and Leech Seed...

Anyway I think Paralysis is most annoying, especially on my sweepers. Confusion/Attraction are annoying...but you can just switch out.

Hello? Freezing? Can't do anything, lasts longer then sleep... the worst status condition by far.

GOD DAMMIT!

Well I guess I can't add it now.

Freezing time, from what I've seen, is MUCH less than sleep, plus, you can only get it when attacked by an Ice move/Tri attack. It also seems to be reliant on low levels.

the chances of getting frozen are much less than sleep, as there is no status move that gets a guaranteed freeze

Also, you can't do anything useful during sleep anyways, besides Snore, which stinks, and Sleep Talk, which usually justs uses Rest. :/

I hate poison/toxic

confusion is also bad, especially when your paralyzed as well

I see you included accuracy reduction in Lowered Stats, but what about when your opponent uses Double Team? Couple that with accuracy reduction and, unless you know Swift, Faint Attack, Shadow Punch, etc., you may never hit your opponent.

By the by, I hate Wallace's Ludicolo!

As annoying as confusion and attraction can be (they replace skill with luck), you can switch out to nulify them. In my opinion sleep is the most annoying status condition, as it basically forces you to switch out and ruins your stategy.

Poison/toxic + confusion

Confusion is the most frustrating. >.> "It hurt itself in its confusion!" >:O Seriously, my pokemon isn't -that- stupid.

Confusion has to be the most annoying, especially when the pokemon shouldn't be affected by the move it hurt itself with. Like a pokemon that has the ability Flash Fire using Flamethrower and taking damage but not getting an increase in stats.

I do too; a Pokemon with Attraction almost never moves, and even worse it never goes away (Freeze for me goes away instantly). This can cripple quite a bit of teams if the genders aren't varied.
