They don't need to fix anything.
They need to fix a lot. Online may not be an issue, butt everything else dealing with playing online is. Freezing, losing belts, getting kicked from 2v2 every match, etc.
They don't need to fix anything. The online's fine for everyone, but, probably you two. You need better routers. Don't swear and complain to them. It's not their issue.
Lol **bleep**, how ignorant can you get?
333 there actually is a LOT wrong with their online modes. I still get put as a different character than i picked, it freezes when looking for opponents frequently, I think the ranking system is HORRIBLY flawed. The reason the mode is called ranked is because you're supposed to face off against people near your level... not get matched with some **bleep** holes who just spam one move and are a much higher level than you so you just get put into a losing slump and drop lower and lower in rank. That's something that would be an easy fix.
