I think this is one of the most reasonable complaints about 4E, but there was an upside - the errata pretty much all significantly improved 4E. It was a vastly better game post-errata than pre-errata, and it allowed them to learn from mistakes rather than making all "bugs" into "features".
I mean, in 3E, the BRV Fighter, ludicrously powerful at release, would probably have been allowed to stand, which would have resulted in a lot of un-fun games where BRV Fighters were present, and annoyed players where they got banned as an option. Everyone loses. By changing it, though, they kept it as an option but kept it playable, too. Everyone wins.
With 5E I hope they test more and need fewer errata, but at the same time, I sincerely hope that when a change is needed, they make it, and don't rely on DMs to ban or house-rule everything for them.
