I like it a lot. Just really wanted to say that. It's just enough to keep you engaged with the game without feeling too punishing. Obviously we're still in the honey moon phase of the expansion and people are still learning the fights and once people get better geared and become knowledgeable with the fights things will change.
I like the overall fight designs in both dungeons and trails. EX1 is probably my favorite Extreme in the game right now (Maybe tied with 6.4 EX if I really think about it) and I'm looking forward to tackling EX2 and the upcoming savage tier.
Please continue to test the limits with what you can do and experiment with in dungeons and trials. Pushing players helps them improve overall and once people do so the feedback of being "too hard" will die down a little bit.
