Japan has practically nothing but 5 bars, they consider 4 bars a bad connection I never even see a 4 bar outside lobby match up, it's always 3 bars or 2 bars in game ¬_¬
4 bars is a bad connection. Compared to offline, it's borderline unplayable. Anything 3 bars or less becomes stupid as hell. 5 bars is the only connection remotely playable online.
