Meddler; @Riot Regarding potential for error and reworks

Just prefacing this by saying I'm not going to jump on you with an "AHA!" when you answer, even if the answer is the one I'm fishing for. That's not the point of this. While I may in the future bug you about this topic, this thread is solely to tell me if there's any willingness on your side for what I'm asking.

The champion roster has been incredibly volatile. With many reworks, and many more reworks planned. There have been some very good ones, some that were bad but have been defended, and some very bad to the point where you guys have even admitted it. Cass for example is being reworked a year after being reworked, and it was known pretty much immediately that the first rework wasn't good.

Should a rework prove to be a mistake, either from a thematic or gameplay direction, is it possible that it would be reverted to the original version? If not then why?

Now I obviously have a specific instance in mind, and to be 100% honest that I'm fishing here, but that should be easy enough to guess from my posts lately and my posts history in general.

Even outside of the one I'd personally like to see reverted, there have been instances where it seems like a change that was made was known to have missed the mark in a horrible way, yet the change is held on to, and the error enforced as the new standard. Trundle, Karma, and Sejuani being the notable examples.

Another separate example. In the case of Cass wouldn't it have been more appropriate to revert the rework when it was understood to have failed, and allow her old kit to remain? At least then her original gameplay and identity would be the starting point for any further changes rather than having the new kit be the point from which changes come; something that could risk compounding the error.

I'm wondering this so I can know if attempting to convince you that a rework was flawed, and the original kit was acceptable, is a viable strategy. If not then I'd probably just end up being that annoying crazy guy that keeps yelling at the fire hydrant for playing it's music too loud.

And I don't want to be that guy.
