I asked Jesse Sky to tell us a little about how Nightmare Mode is going to differ from the existing Hard Mode for EC. He said that the numbers have been tuned up in every fight, and mechanics in every fight have been modified - in some cases, there are new mechanics that players will have to learn. The differences aren't extreme, but they present new challenges in every boss encounters, and the rewards are much more appropriate for the difficulty (unlike in previous Nightmare Modes).
Not really new info, but it is a little more in depth
much appreciated. I'm wondering however, is Nightmare EV and KP still going to be revamped or will it be left as it is? I wouldn't really mind either way, since it's the first tier there's nothing wrong with it being pretty easy, but it would be cool so go back there to find the fights to be a little different and challenging ^^
