I mean, are we changing everything? Greyhawk isn't a load bearing "Only these races have to be playable or everything collapses" setting. Its a bare-bones basic setting based on a homebrew setting that is absolutely based on rule of cool. We are talking about the setting with the god who is a cowboy from Boot Hill and a crashed alien ship. This is a setting that is completely fine with these things existing. There's a whole Martian encounter table in the early books that's just flat out lifted from John CarterWell if you are going to change everything why use any pre-existing settings at all? Just make up a new one and abandon all previous works. And remember as soon as 7e comes up abandon that just created world as well, because you know, strict rules.
I mean, the flavour will be kept, but you and I got very different views of its integrity. Things are being tweaked because, hey, turns out you want the options advertised in the game to be playable in the setting advertising the game.Why is it so hard to just keep the "flavor and integrity" of a world's vision while in good faith judiciously tweaking things as needed? We do it all the time, and others have been with 5e and GH for years. It works, it's being done right now. This seems like arguing just to argue.
Plus like. It takes ten seconds to justify any of the new races. Classes aren't codified in Greyhawk and there's no Weave so, different ways to do magic and not just study, which is the art of wizards. Blam, every single class sorted immediately. Tieflings and Aasimar are easy ones due to the bloodlines, Tieflings with the Iuz connection and just pull an Atlantis with the "Unknown ancient civilisation that were involved with angels" with Aasimar, let people figure it out themselves. Goliaths? Live in the mountains. Orcs? Some orcs and humans fight, but in some places (don't even need to be named) they join together against the wilderness/outside threats. Dragonborn? There literately is something called the Dragon Empire in Greyhawk lore that is never explored (unless you're. Subscribing to the opinion it relates to a French comic which is basically the same as saying "I never want it ever touched ever again")
If those small little adjustments, barely a sentence each, is so much change that its breaking the integrity of Greyhawk to its core, then I have significant questions
