I'm an Infiltration specced Shadow, #2 in DPS for my guild according to parses. I just got swapped out of my regular raiding team because the guild realised I didn't bring anything to a raid beyond DPS.
I can understand why they did it -- the guild's been struggling with hard mode EC and we need every buff and debuff we can. But my fellow DPSers bring more than I do:
Sentinels - Inspiration (+dmg/healing raid buff), Passive raid heals, Armour debuff on the boss Gunslinger - Scrambling field (raid damage shield) Commando/Sage - Off heals, dispels, combat rez, combat CC
Neither of my DPS trees can compete. I previously had use as a very temporary tank in other raids (eg. repositioning Soa under a pyramid if the tank gets mind trapped). Force valour can be applied by other people in the raid, and will progressively become less useful as more people get level 50 consulars in their legacies. Mind Maze has no use in combat. My control abilities (stun, low slash, slow etc) are fairly well mirrored across the dps classes.
What can I do to compete? I'm leveling up a gunslinger for now.
