As expected, a sudden revamp of the way players get information was received horribly.

Remember when you moved the buff bar and people freaked out, Riot? HUD changes can be jarring and seriously impact player performance initially. People adjusted, eventually, but that was just one minor change. This is the buff bar times 50, and on top of that you reworked two champions and started an event on the same patch. It would've made far more sense to start by applying only the aesthetic changes first, and then gradually shift elements around over the course of a few patches. It will likely take weeks before people grow accustomed enough to utilize this new HUD as efficiently as the old one.
