From a WHY WOULD I WANT TO GROUP A RANGER perspective:

If you have a tank, cleric, crowd control, dps, dps, and you're a min-maxer, you add another dps or a shammy for slows/buffs. Chances are, a ranger won't add much to a full group.

If you have a tank and cleric and you want to keep the group small, you add a bard or ranger for that third slot for the versatility.

That being said, most high level rangers on P99 know the odds are stacked against them, and those who have lasted to level 51+ have something to prove, and are damn good players because we know we have had to earn that spot in every group we have ever been invited to.

From a WHY WOULD I WANT TO PLAY A RANGER perspective:

Although soloing is a bitch, you are fairly self-sufficient and it's a fun class to play because of the versatility. You aren't hitting the mob until someone lets you die like a warrior. You aren't medding/casting/afking like a caster. You're tanking, pulling, dragging corpses, asking for rezzes, crowd controlling, slowing (with Swarmcaller), ripping mobs off your AFK casters, buffing, etc, etc, what everyone else said, sometimes changing roles on a moment's notice. Equivalent to a bard, except with less carpal tunnel syndrome.

The problem is, min-maxers don't care you being able to be jack-of-all-trades, master of none.
