No idea man, but all or a combination of those sound like great places to start, you should start a newsletter. I would definitely subscribe.
The point was the game types are so fundamentally different that trying to structure the argument using them against each other was ridiculous. While win rates of PvT, or TvZ, etc... may be indicative of good balance in SC2 (which I have no idea, honestly), it doesn't at all compare to what a hero win rate in LoL or Dota says about game balance.
I wish there were more great RTS out there to compare within the genre. The fact there isn't probably says a lot about just how good Blizzard is at and how difficult it is. I'd say both Riot and Valve do a great job though. The recent Dota patch has been great.
edit: was just thinking back and it made me laugh thinking about some of the old Capcom balance throughout SFIV and stuff with UMvC or Netherealm in MK. It may be hard to tell when these games are really balanced, but when they're broken it is pretty funny but less interesting to watch
