Having combos means no LoS check or it would be hardly playable. Or you'd need to shorten most animation but then again, rangers and combos was always awkward. For example, if you had started salvo on a guy, who breaked LoS before you could start second white hit, you coulddn't fire the second white to keep the combo going before landing the finisher when you retrieved line of sight, like melee would do.
And come on, ranger was never "balanced", it always was the class noobs like me rolled during the first year because it was easy to kill better players with minimum risks.
Other tweaks to make the class more versatile would be great though. Bow and cross bow had their diffrences and that was really good. Now nevermind what you spec it's gonna be the same combos and the same tools you're going to use with very little diffrence.
