Most of you who are unsure about this game would do good to wait indeed. Too many games have been claiming to be the mmo but have delivered us the run-of-the-mill mmo experience with a few "unique" things sprinkled on top.
Here are some of my opinions about some of the features that they've presented to us so far:
Dodging and aiming will only be good if the creatures are challenging enough. I want to be able to say I defeated x or y boss or creature because I was a good player, not because I had the level and abilities needed.
CC seems excellent! Along with dodging and aiming it will make combat very entertaining.
Area hazards, low gravity, secret rooms, etc: I often feel that some of the most exciting battles I've had in many videogame have taken place in dangerous or weird situations in which the area has had traps, lasers, lava, or weird physics. Although the videos show off the low gravity crystals, pollen that makes you float, lasers, and other such things, they haven't really shown combat under these circumstances. I would think it would be crazy not to put the two together.
Paths look amazing, probably the most appealing thing to me. I'm hoping that secret rooms found by the Explorer and Scientist aren't too obvious. It would be a real bummer if it's just something like you having access to this room only because you can activate this machine for being a Scientist. It should have some sort of puzzle.
