Playing xTekken online, getting pretty irritated

I don’t understand this game. I don’t know why every time I press a button during online play my move always gets stuffed. Every single time. What the fuck is going on? Does every character I pick just suck dick or are these the effects of the netcode?

Who do you play and what moves get stuffed by what?

Netcode, also maybe you suck? Hard to tell from your question. I mean you can’t just throw out any move, you need to stick to your character’s good ones. Also, depending on spacing and frame advantage, a “good” move can be guaranteed to never, ever work in certain situations.
