Been playing a lot in the past couple of days, finally got past +25 wins after being on full tilt. Things I've experienced during the past few days:
1) AP Sion is still godly. Haven't used him AP in a long time (since the .1 nerf to Q and W), but he's just as scary as LeBlanc, imo. People keep complaining that mid feeds me (and to report), but people fail to realize that it's incredibly hard to lane against a Sion. Then consider that you can switch from AP to AD later on, and you've got an absolute monster. I know everyone knows that, but still, madness.
2) Jungle Mundo has a freaking amazing clear time; I finished my path by 3:20. I went Cloth + 5 pots to be safe, and it was alright. I wonder if he could go Boots + 3 pots though, like Shyv and Udyr. I do woner what the optimal red and quints are for him though (I assume AS; can't afford them yet, sadly).
3) AP Soraka is a freaking dark horse in mid. It seems to be like a Karma-esque effect: the "idk why [insert champ] is in this lane, so they must be bad" effect. It's nuts, I swear. Sadly, she won't be as strong as the usual AP carry later on, though her heals become legendary. D. Ring start, Revolver next; typical tanky AP stuff (the excpetion being Morello's Evil Tome).
4) I still dislike Taric support. People never seem to realize how mana-intensive he is, and just don't understand him in general. No one follows up on my stuns, like ever. I'll stick to Ali if I want a kill lane on bot...
5) People ragequit in ranked. DON'T EVER FUCKING DO THAT. Had a Karma who quit while we were ahead, and we defended for as long as we could but lost. Ughhhhhhh.
That's it.
