Guild Wars 2

So I have a ranger, and yes now I see that people don´t like them, but I still like him cas I´m a solo player.

My question was how do you improve a ranger´s firing distance?
If you can’t, what do you improve?

This, I feel, is very important since keeping enemies away is the only way to survive with a ranger.

In the Marksmanship trait line there is a Major trait called Eagle’s Eye, it increase the LB range to 1500.
