The MK vs DC Online interface was very very odd and very poorly-executed in my opinion. Here are a few reasons:

When being challenged, you are not able to see the other gamer's stats! This was very odd. Please go back to the older MKA style where you get a seperate screen or at least a popup showing the player's stats.

Allow us to reset our stats and go with a fresh start.

If you confirm a game and the connection is not going to work, the game took forever to try the connection. Give it a reasonable time limit.

When using the on-screen keyboard to type in the chat, you have to press X to pick a letter. If someone challenged you during this time, your x stroke would automatically start the match.

Any other thoughts? I can remember more things irking me but I forget atm. Do you agree? Disagree?
