MK online is absolute tits. Not only is the PS3 version region-locked but I can't face anyone outside of my country because it always disconnects at the character select screen, when I DO get a match it's laggy as hell, and I can't play ranked matches at all. Sometimes I feel like going back to MK9 but then I remember how frustratingly bad the netcode is, along with the unbalanced roster and multiple bugs/glitches.
