I liked how my 30 minutes in WvW led to better PvE buffs. WvW looks pretty messy, though. Repairing a gate 10 supply at a time was painful. Definitely a guild thing. The world also seemed pretty small. I was hoping for something like DAoC where it was a huge spread-out area where you had to run in packs or get ganked.
I also didn't understand the map all that well. I need to spend more time with it.
