Paralyzes(Rush/ShoulderCharge/DeathCall) are the only problem, most other things can be prevented honstly. Open Eyes releases from stun effects but ALSO from roots, you can use it for templar root as well, it works on guard stuns except for Rush(paralyze). As for templar stuns you can use magic guard, which resists the stun since it's a magic attack. Not many people know these things but if you play ranger skillfully you can get around quite some CC. Blue Drain and the paralyzes however remain a big problem.
Another trick is that rangers can be invisible, you can invi if ppl hunt you, they will walk right past you, then once they have their back turned to you and thus their camera is looking in the opposite direction you silence shot them from behind (cast time wont matter coz they wont see it comming). after that you wombo combo their ass to hell....
