Happens to me nearly every time my ranger joins a group. It's hard for me to believe that you are that fortunate.
But then again, it's possible everyone just assumes you are a Barrage ranger. What other elite is there to use? lol -_- I'll be honest, I bet I can count on ONE HAND how many times I've seen a party even ask if anyone is using Barrage. I don't think it has anything to do with people assuming Rangers are using Barrage. I think most people want other skills from a Ranger such as poison or interrupts. I just don't see the big deal about Barrage, most people could care less one way or the other if you use it. I use it above all other Ranger Elite's but I wouldn't say it's my most valuable skill. My two interrupts are my most valuable skills and they aren't elites at all.
I think some people just like to see people using other skills rather than the popular and effective skills. People may call them cookie cutter builds, but they became popular because they work., Plain and simple.

) i equiped BHA. we had 2 rangers in the team, the other one was a B/P with JI. (i like JI but why the pet?...) anyhow of curse i was picking the ele or the monk that the party didnt get to yet and land a BHA on him. should i even say that the poor thing couldnt get a single spell out? BHA is not only bosses shut down, its CASTERS shut down. a Cleric which your team cant get yet cuz of the swarm of dervishes and wariors runing around makes it harder. dazing and shooting the guy makes it so much easier to the team. same goes for those painful air spikers which stand far from the party damage, but somehow manage to spike non stop.
