Well, I'm currently lvl 30 and all I can complain about so far is (if it's worth a complaint):
-increase default range by at least 5m
guess needs no discussion here
-reevaluate casting time on ranged combos
some just seem to be too long
-switching hotbars and weapon set with one button
can do it with g15 though - and also every other class could benefit from that
-fix salvo
salvo shoots 3? arrows - if your target should die with the first arrow, it keeps hitting you until all 3 arrows have been fired - doesn't apply to fatality
-itemization
we can wear medium armor but almost every single piece of medium armor found so far is for tanking +taunt +hate modifier isn't good for us
at level 30 I still wear the lvl 10 medium armor I bought in tortage, wear the legs from tortage, almost everything I wear is from tortage
Itemization is really really bad after tortage
-the chat
not really a ranger only issue

but the chat is fubar
gameplay:
-pve
when I get the opener the mob usually bites the dust before it reaches me
if I pull 2 or more mobs it depends if I can pull the second target into my trap, but usually it's melee time after the first mob
dmg from my point of view is fine
we got a ranged snare and I'm pretty sure more cc ranged combos in higher lvls
-pvp
can't tell much about that
got some world pvp kills, without serious problems unless I got jumped while I was on some mobs
