I like what they've done with optimization.. I was running higher settings than I did in the previous BWE. It really seems as though anyone can run this game, which is great!
I'm definitely set on rolling a Sylvari, I love their lore and how different they are compared to human which is always my first choice. As for professions.. still not sure which frustrates me, they are all so awesome and I could see myself using any one of them however thief is still at the top of the list (read a lot of info saying they are extremely lacking when it comes to PvP.. which upsets me).
One thing I noticed while being in the higher level areas (25+) is that the dynamic events were far slower and less exciting. It's pretty obvious that this is due to the fact that there are less players around but I'm worried that this will be the case quite often when it comes to release. What happens when people are either just starting out or end game, the mid level areas will be a huge grind as there will be no-one else around. I'm sure Anet will come up with something.. still has me worried though. I don't know about you but those DE kept me motivated to keep moving and finishing the hearts, pulling grubs out of a farm can get pretty damn boring.
What about you guys, what are your thoughts/opinions of the game?
EDIT: One thing I forgot to mention was transmutation stones. I absolutely LOVE this idea, appearance is a big factor to me and being able to transfer stats to other pieces of gear is just.. amazing!
