I'm getting absolutely wrecked in game now...

Maybe I just don't understand all the power spikes that are now occuring, or all the possible combinations the new runes have with the different champ kits, but I am getting wrecked in every game now. It's totally not fun or enjoyable. I have no idea what is happening in any given team fight, and the post game screens give zero guidance as to what my enemy team is using (it's still stuck on the old rune/masteries system for some reason).

I'm going to quit this game for a little while until I can sort out wtf is happening, and how to optimize the way that I like to play vs the meta, while not getting absolutely dominated in every stupid freaking game.
