Here are a couple of changes I made in the options for GW2 that I love. Thought I would share them. If anyone else has any they like, feel free to post them.

Options
-Wrench Section
-Chat Filter: Set to none. (I'm an adult)
-Auto Loot:Check (Makes it so when you loot you don't have to click "yes I want it all" or whatever)
-Mouse Section (Added some more keys to the controls)
-Swim down: LEFT SHIFT
-About Face: X (Its so much faster to turn tail with this)
-Nearest Enemy: C (sometimes its hard to target enemies when it is hitting the fan.
