If you're better than your current rating, you'll rise. If not, you'll keep hovering around ~100 Elo.
It's yoloqueue; drop's happen, even 200 Elo drops happen for reasons beyond any of us. You'll get back up though if you're good enough.
Elo hell does not and will not ever exist. There are ragers in every game. There's afkers, and dc'ers in every game. At any Elo. ANT ANY ELO.
I've dropped from 1700 to 1250 for none other reason than because of soloqueue (combined with me playing bad, ofcourse) and then gone right back to 1700. Lucky, I guess?
Anyways, as I've said to Pandragon so very many times before: Get LoLReplay, I'd honest to god love to watch how awesome you guys are, I really would. Oh, and watch Gbay99's video's as awesomeGrading linked earlier; if you still think you are so much better than everyone at your Elo, then I honestly feel sorry for you.
