You know, I've never really understood this argument. Not saying that p2w and Cowboy probably aren't the best Sinestro's. They are the best Sinestro players. However, the idea that unless you play those specific people, out of about the hundred or so people who play this game, you'll have no understanding of the match-up seems a bit exaggerated to me.
So if you were someone preparing for a major, unless you played these two specific people, who may live several states away from you, may play on a different system than you, there is no way you can know how to fight a certain character? I'm not trying to be an ass. Really, I'm not. It's just that this argument has never made any sense to me at all.
It's basically saying, "Unless you fight X and Y, who you may never have a chance to play outside of an event ever, you will lose."
Perhaps I'm missing something. I mean, every character in the game has a set of tools. If you study the frames, look at the tools, and practice scenarios...how can you have no knowledge of the match-up? I'm not saying that training mode or practice will teach you everything. Obviously not. Still, to say that unless you play two specific people out of the hundreds who play Injustice, even still out of the several more people who play this game well, that the average player looking to learn and get better may only see at a tourney itself, seems a bit out there to me. Perhaps you could explain further. Or tell me to die in a fire. I'm perfectly cool with that, too.
Just curious.
