It really did. Alliance were the kings of split push pre 6.79. I think there was a good balance between deathball/split push strats (obviously oversimplifying all of dota into two general strats, but most often fall into one of these two categories, 4 protect 1 is pretty much dead). The last game of TI3 was a perfect example of this, NAVI played their game (deathball), Alliance played theirs (split push), and the game was a tug of war contest until the end where Navi made a few crucial errors.
With 6.79, the game got faster, and swung wayyyy in the direction of deathball. When Nature's Profit is currently the only split pushing hero that can work in competitive (because he's a split pusher that can still show up to teamfights quickly), you know something is wrong. No lycan, no morphling, no AM, no more PL, Syllabear went from being an offlane split-pusher/team-fight hybrid to a safe lane farmer that pretty much only shows up to deathball, etc... The only place where split push is still a problem is AP pubs where you can insta lock Lycan + Brood. The game has changed, the pendulum is now safely on the side of very early 5 man doto.
Personally I'm hoping 6.80 nerfs furion a tad (to help move the spotlight to other heroes that perform a similar role), fixes brood and puts her back in CM, and perhaps nerfs xp/assist bounty with 4-5 people around.
I think it's far too early to start calling for Alliance players' heads, they did just win around 1.5 million dollars recently. I'd give them some time to adapt, maybe see what 6.80 has in store, and if they completely shit the bed at TI4, then you can talk about the team that nearly went undefeated in TI3 breaking up.
