Degraded performance in 2.0?

Did anyone notice a drop in responsiveness yesterday after the 2.0 patch released? Using in-game metrics my ping was reading around 200, which is higher than normal; however, I was getting approximately a full second of input lag in registering move commands and using abilities, which made me wonder if there was something contributing to the problem in the game client.

At first I thought it was just something about Leoric, because he's supposed to be a "slow" hero or something and I haven't used him since 2015, but eventually I noticed that it was on all input and the same thing persisted with Rag and even Tassadar.

For what it's worth, I run an nVidia 10-series card and I haven't updated my drivers yet, so it's not upgrade-related regression.

edit: clarification
