Riot, do you actually think people enjoy watching professional games end in 20 minutes?
Because I hate to break it to you, but they don't. No one will find any interest in Worlds this year if every single game is decided after 5 minutes because blue team already has 7 kills to 0 and they already took bot turret. This isn't exciting. Sure, it's fast paced, but it's also incredibly boring watching one team just eat the other alive for 20 minutes. People want to see games (not all of them, but most of them) stretch out up to 40-50 minutes, where the game is filled with teamfighting and Faker-level plays. We want to see teams which just play better win the game, not just pick stronger champions. You balance your game around pro play and still fail at that. What a shame.
It's also the same thing with sports. For example, with soccer, if all of a sudden the Premier League (or MLS because this is NA boards) had all the games end in utter domination, and 15-0 wins every single time, people would lose interest. Sure, it's good to see every once in a while. when a team gets completely outplayed, but no one wants this to happen every time, because it gets boring.
Riot you need to admit that your balance team hasn't got a clue what they are doing. And no, giving more skins to Ezreal and Miss Fortune will not make us forgive you for the absolutely shocking seasons we've had since pre-season 6.
