I main Ranger everywhere except most dungeons. As pvp goes I ranger all day and LB at that. It does take an incredible amount of skill to be successful but it can be done…easily.
You have to know how to use your builds, you have to know how to use your terrain, and you have to be good at your playing style. You can’t sit in one spot and pew pew spam skill 2. I very rarely lose 1v1 and can be a pain in the neck in 1v2.
Know how to use your pets and taunts. That’s key for helping with survivability.
One big key is knowing who you’re up against each match. Press B, see who is on your team and see who your opponents are then formulate which roll you’ll play.
Again it takes time to master and I don’t even think I’m there yet but don’t let people tell you not to play a class you like because of what the popular opinion is. Personally I believe you can be good at any class YOU master. Just takes time and practice.
Work your build…don’t hope that the build will work itself!
