Just as a quick thing, Rising Thunder wasn't really accessible in any meaningful way — it was simplified in the same sense as simplified Chinese writing, where it's more shortcuts for people who already know how to do something much more complicated. It still played a lot like Street Fighter IV.
If people are doing this, that's… weird? It sounds like someone's trying to show off, really. It's into "taunting" territory. It means that they are so absolutely sure that you aren't going to attack them that they're just going to stand there and mess with you, because you're playing 100% scared. It's ordinarily a terrible strategy because it leaves your opponent wide open to anything you might do other than blocking. Basically, if this is actually happening to you in real life, in games with other people, it means that you're almost certainly playing waaaaaay too defensively — you have to go on offense at some point in order to win, after all!
I will say, though, that with all due respect, you may be overthinking (and over-worrying about) this hypothetical point with regards to a game that you have not yet actually played, in a genre you aren't especially familiar with/proficient in. Throws still punish overly defensive play in this game! You can't get thrown unless you're trying to block and/or move away, so if your opponent comes up close to you, well, you can simply attack them (or throw them, for that matter) when they get close! Or you can use projectiles to make it harder for them to get close.
I'm trying not to simply say "git gud," but in all honesty it sounds like you might benefit greatly from learning about fighting game basics and fundamentals. One of the most important things to learn is how to control space and use your tools to prevent your opponent from getting close in the first place. Perhaps (coincidentally, the same designer's) videos about the fundamentals of Street Fighter II might be helpful? http://www.sirlin.net/articles/street-fighter-tutorial-videos
In a nutshell, though, the main thing that stops the opponent from standing in front of you and throwing you each time you move is all of your attack buttons. Your opponent won't get close if they're afraid of getting hit themselves. If you play too defensively and never attack, they have nothing to fear.
For better or for worse, though, much like any other competitive game, your best bet for improving is finding someone at roughly your own level to play with. It doesn't matter if it's Fantasy Strike or chess or tennis, though — if you play against someone much better than you, you aren't really going to learn anything from the losses, because you're fundamentally playing entirely different games.
But of course, the first step to being great at something is sucking at it for a while! The real challenge is to not get discouraged, and keep at it until you don't suck as much! Not sucking as much is the second step toward greatness!
