"Today’s update is a big one. After gathering feedback from pro players around the world, we’ve made significant changes to weapon balance with global changes to recoil that affect all weapons, as well as specific adjustments to rifles, pistols, and the P90. We’ve also made some changes to the messaging system, so check the notes for details."
From Valve themselves. If you think Dota 2 or any of the other mentioned games are any different when they fill the exact same developer intent of esports/competitive play, then you just have your fingers in your ears.
What you've just shown me, is a change to the game that benefits all players, with the help of the pro's that play it.
Not a change to the game that benefits just the pro's and "fuck you other guys".
