I'll focus on Ul'dah since I spend most of my time there. . . . Loud. That's my first impression @_@ My other impressions would be laggy, prone to crash and a city of invisible people due to game engine being unable to render big groups of people (move 2 steps in Aetherite plaza and you lose half the crowd you just had on the screen).

I do like the influx of people, I'm just mad at SE and the current game engine, but meh. . . . learning to live with it. Also, I'm perhaps not used to hearing whole conversations being carried out in /sh. Not sure how it were on other 2 servers, but Palamecia was rather quiet in that regard (not counting the LFP shouts of course). One thing is certain, it definitely feels more alive now.
