Just a quick note, as this post is a few months old, but figured I'd chime in, in case anyone else has this issue:
I myself play a Warrior, and box a druid, usually only when I want to go off by myself or try for a new challenge with just my two toons.
I often have guildies, friends, and see folks in general chat, all saying same thing: "I've been sitting on LFG for hours" or "Can never find groups"
Me myself, I almost NEVER have had this issue. Find a few friends that you consistently group with, since you play an SK I'd recommend a few clerics you group with regularly, a slower, and some dps. The main issue I'd say is getting the cleric friends, as you can always downgrade to hunting lblues --> Dblues en masse with a hefty Damage shield (if no slower available this equates to significant dps from the DS) and will be able to fill out the rest of the group with a slower if available and DPS classes (caster or melee, though melee dps seems much more common nowadays).
Instead of trying to fill a role in an already established or formed group, start your own, find places that 2-3 people can hunt at, and if you get more folks to join, can stay there or move on to someplace tougher that a bigger group can camp/kill.
Way to many people seem unable to see that forming your own groups, especially if you are a tank, is the quickest way to get from logging on, to hunting quickly and effeciently, picking a place that works for you as a tank. It may be a bit tough/rough in the beginning finding people that will want to join you regularly, but I think you will find, with success and groups that work well together, people want to come back and group again, and will send you tells as soon as you log on asking if you would like to do something. Find this is the case myself, usually within 15 mins of being on i've received several tells from guildies and non guildies alike that know I run good groups (for the content I'm working on) and are always up for killing with me.
Just my 2 cents, and hope it helps
