I normally don't use any type of combo. I usually pull with Tomahawk and than from there it's usually just a random smashing of whats on CD until the mob is dead. I did a couple of story dungeons before when leveling, and the groups I was with were being obnoxious. They kept threatening to kick me out because I wasn't pulling fast enough, wasn't pulling enough mobs at once, and because the Pugilist they had in the group kept getting mobs attacking him because he was doing such high damage and I wasnt able to keep hate on them.

Is it acceptable to explain to the group before entering that I am only in there to complete the story, and that I don't have much experience playing in dungeons, so if they are looking for a quick clear or an easy dungeon, they won't find it with me in the group?
