It's been suggested couple times, but needs reminder.
Too many things are stored on client side right now. Maps for Wretched Gorge, settings for Lava/Mesa, LBF teams, Boss teams, etc. Those of us who are playing on several devices (in my case, phone, tablet and PC bluestacks) have to manually make change to any of those settings on all devices we play.
Store them on server side. It can't take that much space.
