So do I. It's hideous. FAQ erratas by means of "subtle" "clarifications" are bad enough, but forum rulings are even worse. That said the item is clearly absurdly strong, and even at 25k gp it's still worth buying (or banning). I'm mostly annoyed at it being a forum errata and James Jacobs going "the price must be a typo" as a ridiculous excuse to add 20k to the cost and pretend this is somehow not a modification of the rules content.
Reminds me a bit of the FAQ on the Shifter where they nerfed the level scaling damage from Shifter's Edge by half by making up an absurd FAQ question ("Is the damage really meant to be this high?") so they could give themselves an excuse to "clarify" some heavy nerfs. Paizo has some rather awful ways of announcing changes to mechanics, and the retroactive "clarification" method always lends itself to inconsistent rules and absurd gotchas because book C retroactively interprets the rule in book A in a completely different way while book B applies the rule in a different way inconsistent with Book C or a FAQ somewhere completely changes the functionality because of balance issues or some designer not liking it for whatever reason. The result of all this is that Pathfinder is quite awful when it comes to being able to trust the rules text in front of your eyes to actually work as the text in front of you describes. I've mentioned the "actions at a distance" programming anti-pattern before and "rulesbook modifications at a distance" are vastly more perverse.
The fact that paizo's own designers cannot keep their rules straight and occasionally write new content that relies on rules functioning differently from the latest rulings just adds to the mess. Then again Pathfinder Core was the beneficiary of a series of rules "simplifications" which resulted in missing blocks of rules texts and rules no longer making sense, causing people to refer back to 3.5E to attain a consistent ruling, except when PF differed from this, especially in the retroactive "this is how it always worked (even though 3.5E has clear examples to the contrary)" sense, like no longer permitting people to combine armor spikes with 2H weapons in TWF or not permitting people to take 5-foot steps during a Cleave for some bizarre reason.
Hell PF has a lot of content that is blatantly odds with how the rules work as described by Core. For instance, there are a number of class archetypes that require you to have taken a feat at 1st level before taking the class, or if you use
Racial Heritage to qualify for a racial class archetype at 1st level for that matter, even though in PF Core you explicitly have to take feats
after class levels.
PF has always been a goddamn mess, honestly.
