Damage in the new patch

Is it just me, or has damage (at all stages of the game) gone up by far more than the latest routine nerfs to tank stats/items would indicate? It seems like everyone is melting at a much faster rate than before the patch.

I realize that this is in line with Riot's goal of turning LoL into the WWF of esports and is probably just another blow in their unholy crusade against tanks, survivability, and east coast players, but I can't seem to find HOW they did it - I didn't see anything in the patch notes that would account for this degree of change.
