Yeah I agree.

At this point you should never be in a situation where you cannot buy games that are in the genres you enjoy that are 1+ years old, as a result patched up, and on a 30%-70% sale if you're willing to wait at most a few weeks for the next sale.

And since there'll be more than 1 such game, you can always have one on backlog while waiting for the next one to go on sale. There's 0 reason to buy the buggy full-price on-release version.
