I like that we got mentioned...
...but there's a difference between the reasoning behind the waylay errata and the reasoning behind any other potential errata. This distinction is important to remember before we start talking about casual players not liking errata.
Waylay's errata was good for ending rampant abuse of the card's timing rules. What was bad about it, what I presume the founders took issue with, and what I take issue with, is that the errata prevented people from using other cards to give haste.
Certainly as that involves another card, the power level goes down, so it isn't abusive. The course of the game does not swing wildly when it is used in this way. It could have been erattaed so that the tokens died at the beginning of a turn, because combat only instants are lame.
However I don't know how many casual players would get sad about Illusions of Grandeur errata.
That card's flaw is because of old expectations about card use that were in the minds of the designers of Ice Age. That set was at one point slated to be the first expansion! It still tells you to choose a target for local enchantments when you play them! Maybe they were errataed after the fact... but keep in mind there is technically nothing wrong with your Regeneration targeting a random creature, or the enchanted creature. Enchantments can have targets outside of the cards they enchant; at least I don't see any reason why they'd make a rule against it.
So sure, Illusions is still functional...
Yet they errataed those other cards, which were made with other expectations for use in mind.
I doubt whoever designed Illusions of Grandeur expected it to be combined with donate, because nothing like Donate existed at the time. You could exchange control of stuff, including creatures and land, and you could copy stuff, and you could take stuff, but except maybe for steal enchantment (if there was one anyway) enchantments were exempt, IIRC. Also no one thought of giving stuff away, EXCEPT MaRo. Good for him.
Cards may be rotated or nudged into disuse, OR they may be errataed. These are different solutions to different problems, and each is useful, so we shouldn't overlook either.
Errata Illusions of Grandeur, please.
We can unban Dark Ritual in extended now too.
While we're at it let's reopen the waylay debate, for old times' sake.
