Other than the normal 3-frame-uppercut dudes, and Dhalsim/Akuma/E.Ryu with their teleports, who can't be safe jumped? I've heard that grapplers can't be safe jumped either but I'm not sure I understand why.
Also is there any certain character that it's good to practice safe jumps on? Or any tips to make them more consistent? I've been having a lot of trouble with Vega's safe jump (whiff cr. strong after EX Izuna) and I'm not entirely sure how to figure out what's going wrong. All I can tell is that I'm consistently being hit by Rising Jaguar every time I try. I've also tried doing it on Guile, but couldn't get it either. The only character I've successfully safe jumped is Sagat and that was only when I switched to whiffing cr. forward instead of cr. strong.
