Freeze Status: Honestly, nothing wrong with it, I just gotta help teach noobs not to break all the iced enemies.
Fire: Develop a straight damage per second instead of per 1.5/2secs (can't remember which) it would make the status much more relevant to us in many cases. (Not just an FSC status that kills us)
Curse: Attempt to develop a manner of minor and moderate version of this status. It would be useful for multiple lines. I don't know how you develop your 'ban' coding, but I think knowing how much ban shouldn't be difficult. Perhaps allow strong to ban everything, moderate to ban 2 out of 4, and minor to just ban 1 of 4 weps. (involving ban on us) As far as how it goes about damaging everything... keep it.
Shock: This would appear to be a status with little need for fixing... it's a wonderfully annoying status for almost anyone afflicted.
Poison: This status... yields very little for us. I find that almost all of it yields minimal results at best. While giving monster families almost all advantages. They seem to get a 30% damage buff when we're poisoned... why can't we get the same back? In place of our STRONG version being only a 7% increase?
The attack debuff should remain the same... but we really could use more damage buff for inflicting the status.
Stun: Fix the bugs. That simple. We can go from that point forward.
Sleep: This status shouldn't even exist anymore... sorry.
I think I can agree with most of what you've written here, except for freeze. If damage is done no matter how enemies are broken out of the status, it's got potential to be overpowered. Leave an enemy in the haze cloud from a Freezing Vaporizer (or subsequent upgrade) and knock it with a Cutter or something every time the enemy freezes. Boom - tons of damage dealt.
The way I see it, freeze is balanced as-is. The reason it doesn't do damage when enemies are broken out is because there's a tradeoff when you use freeze: you can leave an enemy frozen by not hitting it and have freeze deal damage when that enemy thaws, or you can forfeit that "thaw damage" and instead deal your own damage to that enemy.
I hope that made sense. It's past 2am here and I'm basically sleeping right now. Herp derp.
