I think stupidity proc should stop doing anything that costs balance or EQ, like secrets. The classes nowadays have sped up so much, with efficient curing and offense, a single stupidity proc that makes you do secrets can cost you an entire fight, and I think that spoils the fun. There are classes that can stick stupidity and confusion a lot and not letting you cure them quickly, a secrets proccing at this time is terrible, and the chance for it to proc immediately again is always there.
I suggest to remove actions that costs balance and equilibrium like SECRETS from stupidity. The proc rate blocking actions are good enough hinder and they are acceptable.
