Before you start playing ranked...
Please for the love of God, get rune pages for the roles that you play. I don't know how many times I have seen a support, etc. with only cdr glyphs or other inappropriate or incomplete rune pages. Also, please understand how pick order works, call order does not exist in ranked. If you "top or feed," then you are exclusively the reason why you can't get out of ELO hell. Lastly, don't you dare try anything new, "first time blitz lol." Yes, I can usually tell without you telling me you are playing them for the first time. Stick with what you know how to play, and before you take it out into ranked practice that champ in whatever role in teambuilder, or whatever. I'm sorry, but this has been my experience lately, and I had to rant about it.
