My main is a ranger and your way off base on your issue here, you need to leave the wvw if you can’t handle getting killed. I can tell you for first hand ever other class is a pain in my butt and I love the challenge. Now thiefs are nasty when they get up on your backside, a few hits and your dead, don’t see me crying.
Learn to move and stay out the incoming arrows! lol
Only thing I was trying to figure out is how some get some 5k to 6k hits over and over and take no damage. I know I have 12lvls before becoming a lvl 80 and I will see that kind of dps, heck there are like walking gods at time, lol
