I just spent an hour play exhibition games to learning how to block glacius and orchid. There are two blocks: hold back and hold back and down. With jump ins you can't hold back and down, with low kicks, you can't just hold back. So you have to learn how to react fast. Usually some one with jump in then do a low kick, so you block high then block low. It takes some practice, but it feels a lot like the original KI. Also combo breakers are easier on the linkers, you can only link light and medium, so you have a 50% chance of guessing right. The biggest thing I hate is the wake ups are as strong as KI, they work, but I loved the original wake ups, especially orchids.
