First of all, I'm very happy with how this game is turning out to be, but there were some things seen in the latest video I'd like to be changed.
Get rid of the minimap and replace it with a Skyrim style compass at the top of the screen. The more minimal the HUD, the better.
Also get rid of the flashy effects when you hit an enemy. The floating claw marks and such make it look just like all other MMORPGs out there. Just use a blood splatter to indicate a succesful hit.
One more thing. I assume the jungle with the Mayan looking ruins is Black Marsh. The thing is, when I hear the word "Black Marsh", I don't think of a lush, green jungle. I think it should be really foggy and the green plants should be a lot darker in color. But that's just my opinion.
