They're making a lot of changes in the coming months that will supposedly appeal to those who were less than thrilled about it's implementation. These changes look to be more aimed towards casual players, who lost interest with all the button mashing. Plus "Legacy Mode" is probably going to be put in development soon. It's hard to explain, but the short and sweet of it is they're going to explore reinstating the old combat system as a toggle option.
As for EOC as it stands right now, it's easy enough to get used to. Kills come faster, on average, than they used to. Your best option is to go into the game and do whatever it is you used to do and see how much has changed and if you like it or not.
