Ok, so you've missed out on a bit.
Kassadin is still broken op, but Teemo now stands next to him.
Rammus and WW sort of fell out of favor, although they are both still really damn strong, Urgot has also fallen from grace a bit, although he is also still really strong.
Ezreal is the strongest overall ADC, Eve got reworked and is now op, Sejuani is actually viable now and is slated for more buffs, and bot lane dynamics have shifted around slightly.
You shouldn't have *too* much trouble getting back into it. Just spend a few days shaking off the rust and you'll be fine.
Oh yeah, and draft is dead as a doornail. R.I.P. Dominion draft.
By far the best place to hang to get a feel for the meta and stuff would be the DominateDominion chatroom.
Join us, and go ahead and set the room to auto-join at startup while you're at it ^_^
