There is a profound limitation to simply allowing the distributed network of argumentative online posters to determine what rules are "broken" and in need of fixing. For a textbook example, look at 3.5 D&D. They don't playtest at all, and the result makes us very sad.
What they do instead is put out books as fast as they can, and then watch for the number of people who complain about things. If it's "abnormally large", they investigate changing it in upcoming publications. If that causes the complaints to go down, they call it a successful fix and move on. Repeat as necessary, it's cheaper than delaying publication to wait for Playtesters (because we know those fuckers are lazy bastards anyway!)
Right? Sort of.
That system is actually really bad at identifying and eliminating actual infinite power loops and other "truly broken" mechanics. Once you
wish for
more wishes there isn't a lot to
say, and thus the total internet chatter on that topic is rather low (even if it is both scathing and compelling when it does crop up). But perhaps the more important problem is that it is bad at identifying problematic rules which are hard to interpret.
The classic example of this second case is D&D
Polymorph. It's actually the source of nearly half of the confirmed infinite power loops from Core 3.5 D&D spells (
Balor Mining, Chain Binding, Free Vaction, More Wishes,
Phoenix Duplication, Re-Awakening, Santa's Workshop,
Spell Reserve). And it still does that, despite the fact that revisions in D&D rules have dropped Polymorph balance complaints to virtually nothing. And how did they do that? By making the spell chain
incomprehensible.
Let's say that you were a 15th level Wizard who wanted to take advantage of
Spell Reserve - a relatively simple infinite power loop where every day you can cast 3 spells that will
each give you an entirely new set of daily spells, each of which could itself contain 3 or more resets on your daily spells. Now to do this all you need to do is use
polymorph any object to transform yourself into a creature with the "spellcasting" ability and pick up those spells and cast from that reserve instead of your normal reserve until eventually it comes time to
do it again (and again use the bonus spellcasting to transform yourself). But
first you'll need to
actually read the spell! that's hard. To get the complete text, you'll need to read the following (listed in order of precedence in rules strength, not necessarily in the order you'll actually read them):
- Polymorph Any Object Errata (net)
- Polymorph Any Object Spell (PHB)
- Polymorph Errata (Net)
- Polymorph Spell (PHB)
- Alter Self Errata (Net)
- Alter Self Spell (PHB)
- Polymorph Subschool Rules (PHB II)
- Black Ethergaunt Monster Description (Fiend Folio)
And sure, when you're done it comeplete unambiguously says that every time a 15th level Wizard casts an 8th level spell on himself (or any of his friends), he can grant them the ability to cast spells as a 17th level Wizard in addition to whatever it is that they were doing before. But seriously, that's
eight fucking lines of inheritance! And
none of them actually have a pointer to both the text above and the text below them in inheritance hierarchy.
So have people calmed down in complaining about Polymorph now? You bet they have! The number of people who can even
read the entire spell is actually very small because it's spread across seven different segments in three different books - one of which is not even for sale.

So that's a serious danger when you run game balance by committy. Just because people have stopped complaining about how broken something is doesn't actually mean it isn't broken. In fact, Spell Reserve only became possible when the Polymorph Subschool Rules in the PHB II threw in the side jab that any ability that a monster had which wasn't specifically mentioned anywhere else in the spell's effect hierarchy was granted to the player - which has very little effect except to make the "Spellcasting" ability transfer over to your new form.
