Define the problems. I personally didn't find all that much badly wrong with it before the datapack in terms of controlling the gameplay and very little has changed afterwards. One thing that is different is that defenders can't catch attackers quite as quick as before. While thats good, it does mean lob through balls can be abused a little more as a result. Not as bad as last year, although it means they can be too easy to pull off now. Lob through balls need to be far more harder to the get the power right on them.
Cursor change can be irritating as usual when you sometimes can't get control of the right player, which can be fatal. Thats the same as last year though.
Online can be laggy, other times its great. It's ok overall but could do with improvement. I don't know how well 2013 is online at the moment so I can't compare. What other issues have you?
