In order for League of Legends to be healthy, experimental play needs to be heavily encouraged.
When's the last time you experimented in a game and didn't hear anyone say "what in the fuck are you building".
I'm going to bet at least not in several blue moons.
Everyone's too uptight. I can't even go into a normal game and experiment with my builds in a casual match because normals aren't normals anymore. They're ranked games that don't count. And I get it. Everyone likes to win. No one actually likes to lose. But holy hell people, get a grip. The pros don't know everything. Not all the knowledge in the world is posted on a wiki page, or guides website, or a youtube video. Have some fun.
No one seems to be doing that anymore.
