My main toon is a shout guardian which rocks in fractals, but people want damage over survivability for speedruns, so I started trying to use my warrior. Part of the problem might be that I haven't played my warrior as much as some of my other toons, though I know when to place banners and I know to keep FGJ up, so most is self explanatory. When I did play warrior I used to go axe/axe or axe/mace, so GS is relatively new to me (though also self explanatory.)
In other words, I'm sure you're right about sonic boon warriors, and I may try one in fractals if I bring my warrior instead of my guardian next time I go in.
I guess I am pretty sheltered due to having a guild group that I run 6 nights a week to do dungeons and fractals. I didn't think that the community of this game was that bad. Honestly if I was in your situation I would spec sonic boon and lie to the idiots to get in the group. They deserve it.
