So, my usual response to this having played only a ranger in EQ for 20+ years is: The ranger class is odd in that it is a lot of fun to play, but only from the ranger's perspective, not anyone else's.
As others have said, and this is completely true... if you aren't seamlessly transitioning when needed between:
- DPS
- rootparking or kiting adds if no other CC is available
- pulling
- harmony-splitting
- harmonying/invising your way to a named on track and bringing back solo to the group or with minimal adds
- staggering the timing of incoming mobs with root and snare if you're indoors or your group has an enchanter so they don't want one harmony-pulled mob at a time
- snap aggroing shit off the caster that just overnuked
- yanking a mob off an enchanter that just had mez/charm resisted
- rooting a mezzed mob before the tank attacks it in case the enchanter still has aggro
- topping casters with ranger heals so the healer can focus on the tank; and
- avoiding aggro otherwise so you don't become a mana drain for others
then you're just a low-DPS rogue with some spells. Not to mention you're making it more difficult for every other ranger to get invited to a group when you don't play one to its fullest potential. That takes a lot of focus and stamina to keep that level of play up for hours while grouping, but I guarantee you are having more fun than the tank or the rogue.
It's a lot like the difference between a bard who just stands there and plays manasong, and a bard who is twisting multiple songs and is using the full potential of their class -- you all have played with each kind of bard, and you know which kind you want in your group.
Same with rangers.
