League of Legends (LoL) Question: Can I submit ideas and adjustments to Riot Games?

If you can, could you possibly tell me where to go? I was wondering because fiddlesticks' power has been reduced ever since the runeglaive came aboard. I was thinking maybe rework his E a little bit to add on-hit effects to it on the first champion hit, or another alternative would be to have the regular AP enchant back, and just have runeglaive as a secondary jungle item, like Warrior, and Devourer. I feel like fiddlesticks was the thing that made jungling fun for me, and taking away the only role he could call dear just seems wrong to me...
