Yes, you did do that. Don't be ashamed. Embrace it!
And I get what you're saying and I'll grant that it's not always soap with cancer chemicals situation. But that doesn't mean moving forward with a bad patch is the only available option either. However, it seems to be the only option Riot's been taking. The other one is available and valid but consistently ignored.
There's a difference between a bad patch that requires reverting and one that doesn't. If they changed stuff in a way that (like you said) changed things for the better, but the champion ended up in a bad place, by all means keep the change and mess with the numbers to improve them. I don't think anyone's really complained when this happened.
But if you change things in a way that just made things worse all around, there's no shame in reverting it and do an alternative. This is what ends up getting all the backlash, because Riot seems to refuse to take this option. No one's saying this option must be taken every time, but it isn't taken even when it's a good time to do so.
Kog'Maw's attack speed passive being moved from Q to W is an example of the latter.
Before, it made you think about what you needed: more attack speed and shred from Q, or more range and lower down time for W. Now it's W, no question.
Before, the power of each individual skill was slightly more balanced, though W was still a tad overloaded. Now W is completely overloaded with all-the-things.
And on top of all this, it moved Kog'Maw into OP status somehow. Messing with the numbers at this point may "fix" his status, but his changes still left him in a worse state, not a better one.
