What do you want to see in LoL?

Play a premade 5 and experiment. People like to use what's been proven to work well. The meta is constantly changing.

I personally want an integrated replay system and a better skin preview system before purchasing it...besides going out to youtube or something.

I should not need to play with 4 other people that i know to do something else than 1-1-2 + jungle.
I just find it boring that, that is pretty much how 99% of the games in MM turn out and people rage if you try something different.

Edit: Note, i don't just pineapple around and ruin peoples games, but i find it annoying that trying something new makes people rage. If i want to try something, it's because i have an idea behind it, not just to pineapple around.
