Okay so maybe I'm missing somthing...

Everyone is complaining about damage right? So why in the hell would riot nerf shields? Like the fuck that's kind of a last line of defense against damage right? Like why not nerf the damage first then take a look at the shields? I get that Janna is obnoxious but I feel like her shield is not the issue so much as her w's damage. Am I crazy? Is there something I'm missing?! Like shit I know I am low elo but I have played enough of support to catch onto a few things but maybe there is a puzzle piece that I am missing?[zombie-brand-mindblown]
Or is this gonna be a yesterdays issue in the next month because Riot likes to change shit so damn often.
