To all of the "6.18 is for the pros" people
It definitely is aimed at higher tier gameplay. They're the people who can use these champions to the maximum(or near) efficiency, and to have the same champions picked and banned like last year would lead to yet another somewhat disappointed viewership.
And to all of those "They're balancing for the pros for $$$$$$$$! SHAME! SHAME!" people Well, on a f2p game, you'd better do something for money. Nobody is going to put a 40-hour week into balancing and maintaining a game that doesn't pay anything. It's not that people wouldn't like to, it's basic economics. You need food and shelter. Those aren't free. You need money to accommodate living expenses. If you spend your life giving away everything you have, including your time, you'll have nothing for yourself. There might be some self-centered greed in there somewhere, but it pales in comparison to their overall fiscal agenda. That's not saying their entire goal is financial gains out of it; more interesting picks makes it a more interesting event to watch! Even if there were only a couple hundred viewers.
Just thought I'd throw out my two cents since so many others seem to. Sorry if my thoughts seem a little scattered. :)
