I've played more than enough of AA to confirm that I'll be playing at launch. I've achieved most of what I wanted to try out during Alpha. I've certainly played more than I have during a pre-release for any other MMO.
I still have plenty to look forward to at launch. I've done so little of the quest content and haven't stepped foot in a single dungeon. I did some healing in a max level PVP zone while guild members were farming XP, leveling alternative skills sets and unique drops. No one engaged enemy faction while we were at it. It reminded me of the impromptu detentes on PVP servers during in Burning Crusade. Farming motes was bad enough without fucking around with each other. This particular set of are elite, tightly packed and respawn rather quickly. Jacking around with each other would mean insta-death and greifing each other back and forth wouldn't accomplish much.
I've been out of town on business this week. Guild members are looking after my property, farming my trees on my behalf. I'm looking forward to getting back home and relaxing in game for a few hours.
Although I consider myself done with the Alpha, I will be playing but a bit less. Recently promoted as a guild officer, I don't want to lose touch with the gang. Plus they're a real hoot in vent.
