Back After 3 Months

So, after three months of a break, I got roped back into LoL. But I've been gone for so long, and wasn't terribly awesome to start with. So now, I'm looking to get back into and possibly actually get a bit better. So I'm looking for help/tips/updates on whats changed and what to do.

General Info:

I prefer Mid and Support. I almost exclusively play SoloQ and TB. One thing I probably don't need help with is warding; I'm a warding monster, no matter the role I'm playing. If anything, I probably spend a little [I]too much[/I] on wards when I play Mid/ADC. No, I'm not toxic nor mean to my teammates. I barely talk to them and mostly use pings because A: I don't want to get reported and B: Typing distracts from playing. I don't fight people for roles; though I do call what I want. Its about 40% of me getting what I want.

As for the champions I like to play, the picks by role are (if I can get what I want):

Support

Mid

Jungle

Top

ADC
