I think that Waylay should have never gotten errata because now white pretty much sux except to splash disenchants or something. Then again this is only my opinion.
Definately repeal the errata, at the shop where I play, anyone in our casual games is allowed to play it during the wayalay step.
Its funny when people whine about it.
Well, a bit late but since I just got here I might as well vote on this and the other issues:
As the original question goes at the beginning of the thread, repeal the errata.
BUT!
Still change it so it's more in line with what it did before (changing the "At end of turn" to "until end of turn" should do).
Until a comprehensive study is done to ALL the cards to see how the end step affects them and changes their functionality, keep the end step on the watch list.
