Well, after getting gold( 1524 ish) , i am back down to about 1450 in an epic run of fail games, so i stand by my original sentiment that its all down to luck and nothing you do makes any difference. The problem is you hit a wall in about 1400-1550 whereby there are still enough noobs in the pool that have arrived there by chance that they massively **** up the game. I had a game at 1500 where I was support laning with an ashe who had 12 ranked wins, in total. He originally wanted to pick renekton into bot lane. 1500 elo and i had to explain to the ashe he needs to concentrate on last hitting only, not pushing the lane. That sort of **** is beyond a joke!
I've said it time and time again and no doubt my figures have changed but roughly here it is...
Started playing ranked lost 5 in a row, gave it a few weeks played again, won 8 in a row, then lost 8 in a row, then won 2/3 lost 1, got to about 23 or 24 wins and 18 losses now had another 4 game lose streak I think it is.
It's total luck, I was saying to Deiwos I'm an OK support and I'm happy to play support as I feel him jungling is better than me taking any role, but when your with carrys who don't know how to play you're stuck.
I agree it is 100% about luck, had a 1650 Ashe feed because my friend chose Soraka to support him in bot and he said Soraka was useless after the nerf.
I want to do ranked so much, I have fun in normals but it's not the same as solo top etc, I hate being in lane with another carry/dps when I need CS too as one person gets under farmed so I love ranked for that reason.
Enjoyed last nights quick game as Vlad, I was dominating mid with help from ganks I feel as Vlad, just every team fight Garen would just charge to silence me and they would nuke me out

Was rather annoying.
-edit-
That Gragas Dash and Ulti was amazing, prob best thing I've ever seen!
