[quote name='Rei no Otaku']Have to agree with Chac, most of the people online are scrubs. While there were a couple people I fought who knew what they were doing, most of the time it was just people flailing around on the controller. Not even doing combos or anything. Just hitting the buttons.[/quote]
That's always going to be the case though. In an arcade, you're almost guaranteed to fight against people who know what they're doing or willing to learn.
Online play, everyone and their mother will sign up and use the service for free. You'll encounter a lot of bad players. And even those who are decent at fighting games, this may be their first entry into the SC series. Considering that this is the first online experience for SC, it's bound to happen.
I remember when playing DOA4 online, the disparity amongst players was enormous. All it means to me is that more people are enjoying the series, which I think is a good thing. Something SC4 might want to do, however, is create a ranking system LIKE DOA4 did so that you know what class of player you and your opponent are.
