You missed my point: New strategies are not invented by any one person so much as they are tried by some, and if those few find success they repeat it, and due to exposure, others will start trying it, etc. That's how meta's change, people find things that work by experimenting, others see the successes, and then gradually start adopting what they see working (or adapting it to other roles/champions/etc.), and the way the game is played changes because of it.
I was perfectly on topic in saying what I said, you just didn't recognize that it was. By the way, I did decide on my own to try and play bot lane aggressively back then, not because I saw others do it, but because I had deduced that it was advantageous to deny my enemy by zoning them off the CS and ruining their farm, and that I could do so by positioning aggressively and punishing them every time they tried to CS. It was an invention by me, but others also invented it on their own (and I can only assume some did so before I did). So I was a part of the small number of players that had figured out a new strategy, which proved to be better than the existing meta, so it replaced the existing meta. If the new strat isn't better than the meta, but also isn't worse than it, then it may or may not 'take off' and even if it does, is unlikely to fully replace the old meta.
Also, most of the time, the people that come up with new things that eventually enter the meta aren't people whose names you'll recognize. You might know if someone popularized a particular thing (ex: OMG Cool making Syndra meta in NA by dumpstering TSM w/ her back in season 3 worlds. (This game: https://www.youtube.com/watch?feature=player_embedded&v=Qc81rqma428&t=19271 ) I was also among those playing her before that happened, btw. I knew she was good just from reading her kit when she was released and had gotten around to getting her and starting to learn her by the time that happened), but you won't know of the many other people who were there, doing the same things across various elos and servers. The OP's rant is actually pretty on-point: people do have a tendency to hate on anyone who doesn't do the meta things, without seeming to stop and ask themselves: "Does it actually make sense?" Most people seem to ascribe to the incorrect idea that the meta=what is good in the game. The reality is that the meta is: What people are playing (which usually is a subset of what is good; that is, there are things that aren't being played that are actually good).
