I manly play WvW. I run zerkers with travelers. My build is based off the same build one of the best mesmers I have EVER seen. In fact he schooled me but good. In WvW, you are not gonna run across a fair fight. Gank Squads are just waiting for ya. Invisibility Is the key to helping the mesmer survive in WvW. I can stack about 15 seconds with a extended blink trait that can get me out of any thing.
Null field is your best friend. I spent a day in pvp with a friend that was a necro. I let him hit me with all his conditions. It took him forever to kill me, and in open world, I would of been LONG gone. Decoy is another must have trait. Fought a Dragon, he threw fear, I threw decoy, and I went no where. Blink is the third must have. You can really move around, even bound, and that gets you out of the kill zone.
I look at my mesmer as support for the group. I play the tiny race, and I am the mesmer that helps the zerg retake major objectives. If we are gonna loose the hills, or keep, or bay, well I am gonna do my best to hide so we can get it back asap. Still finding nice little hiding spots. My success rate is pretty good.
The key to a great mesmer is practice. Try different spots above and across to see if blink will work. Look around and think out side of the box for hiding spots. You would be amazed at all the spots normal sweeps always miss. Will it work every time, NO, but it will work lots of times and is a hoot when you get away with it.
Arkane thievery, is simply a waste, I run gs, for back line zerg fights, Throw null field on my team to remove conditions, Have a sword if a thief thinks he is gonna gank me, and my torch to go invisible. (the cleansing torch trait, not real great.). I run a 4 4 6. They cant hit you with conditons if they cant see you. Oh, one last thing. I can solo orr no issues. GS for range, and nice sword skills for the ones that are dumb enough to get in my face.
