Just an update.
Lag is less as the player base has spread out....still too much in some areas, but more tolerable.
T7 raiding is a challenge, but I like it.
In terms of the overall design of this expansion, I have to say it is above average. I have been pleased. Neat mobs, neat instances, neat inside zones with significant quests and decent equipment upgrades. Travel is more of a hassle tho. We are using spires and clouds (a tad bugg, the clouds) to zone up and fly around.
I am currently 66, though more than half my guild is 70 and doing AA's. They are not terribly significant but helpful.
AA's in EQII are more of a choice. You have 5 different paths (based on str, int, wis, stam, agil) and a max of 8 points in each of 4 or 5 levels down each path...with a max of 50 points allowed, so far. So you have to make a significant choice for your toon.
