I'm mostly miffed they removed Air Blocking because it was extremely useful and kind of an important part of my fighting style. While it has technical similarities to SFIII, I feel that SFIII was handled better and the Parry system really changed things, whereas the Focus/Revenge Counter system doesn't quite feel as polished as the Parry/Alpha Counters, its mostly there for advanced players and dealing with the new characters cheap move sets. I also feel the incredibly short turn arounds for Super SFIV and the next version update were also pretty annoying. At least there was some time in-between the older entries to get accustomed before they released an upgraded version. Wasn't the difference between SFIV and Super SFIV like only a year?
