95% of the errata for the PHB1 is to update wordings and formattings to keep them in line with later books and clarify ambiguity along with a few typographical errors. Very VERY few balance changes were actually implemented and none of them were so horrible that they would ruin your average game, but that they presented certain problems to organized play.
Disagree.
There are quite a few balance and design problems. Like the expanded crit ranges on paragon paths open to anyone who can take a feat. The veteran's armour. The size of epic area effect powers.
And so many more problems that could have been spotted by a little extra editing. Such as the paladin build that lacked a power at one level (I think there was a warlock power like that too).
Because the edition was young and knowledge of the system was rougher, a lot of the problems are excusable. They just didn't know.
But as the edition continued so did the errata, with regular large updates after every book. Stuff that should have been caught by even a cursory editing pass. Like the battlerager fighter, whose problems should have been obvious after a single playtest session.
I think it was at its worst in 2010 when it seemed like they weren't even trying to do last minute editing figuring they could catch it as an update.
The fact that they actually did errata things as opposed to just leaving them broken does not somehow make 4e a magically more busted system than any other version of D&D. 3e is, objectively, far worse in this regard. There is no errata and Pun Pun and friends are completely legal characters.
I didn't bring up editions. I brought up WotC and its glut of books, which covered most of 3.5e as much as 4e. The monthly content being generated faster than it could be tested. That's a problem regardless of edition.
I was asked directly what the most broken book for 4e was and answered. I could also tell you my pick for the worst 3.5e book.
Now, 4e was a *little* worse for this because it had a much higher crunch:fluff ratio, so there was that much more content to generate in the same time. And the balance was much tighter, broken options stood out more.
You're just villainizing the edition for actually giving a **** about clarity and presentation and using the options available to it to help people who might be confused or frustrated while implicitly giving other games that won't admit their mistakes a free pass. That's pretty unfair.
You're making it about editions, not me. I was trying to discuss WotC's former practices in general, recalling how they managed to repeat a lot of TSR's mistakes (and start a reminder of what not to do next time).
