Recovery timing on dashes have been changed. In many cases, a few attacks have had added recovery frames, including heavies, which means that your dash timing will be off. Same applies to forward throws.
Again, it just seems to me like its a lot of the added start up & recovery frames on medium & heavy attacks across the board.
Dash recovery is a universal change, or for the specific characters indicated in the PDF?
Take Mika's Brimstone loop, for example. The PDF doesn't indicate that anything about that move's recovery or frame data has changed. However, I've had to relearn the timing for the loop from scratch ever since the update.
