There are multiple ways to deal with and counter throws. You can “tech” the throw, you can jump away from a throw just as it starts up, you can attack and beat a throw with any attack that has a 3 frame start up or faster(which is the general speed the most light attacks come out at) which leads to a combo, in wake up situations you can even throw someone before they throw you simply because you have an attack advantage on wake up.
That fact is, throws are actually not very good in CvS2. You have a variety of ways to counter them affectively for a decent amount of damage. If your not countering them affectively, you’re ether bieng strait up out played(you’re guessing wrong in every situation where you’re forced to guess), or your reaction time is a little slow.
I think this problem largely comes from playing KOF honestly. In most KOFs normal throws are absolutely awful. In KOF teching a throw is ridiculously easy, you can even tech a throw at ANY time, even if your recovering from an attack or in the middle of a roll, which makes no sense. To make matters worse, the window after you leave block stun where you cannot throw someone in KOF is about 10 frames longer then it should be(this was changed in KOF2k3 however). It makes throw attempts EXTREMELY obvious as you have to wait a year after they block a light attack with frame advantage after it before you can actually throw them, giving your opponent a huge window to counter you. This makes any sort of real throw mix up way too risky, making most players just resort to basic low jump patterns, which end up bieng blocked anyways because you can react to them.
You should simply buckle down and learn how to counter throws.
Attack/throw guessing games are a basic part of most fighting games. You already have more options for dealing with throws then you should. It’s very much not the other players fault nor is it the games fault. If your losing to throws your opponent is simply spotting your weakness and taking advantage of it.
