Yeah, let me just go back in time and download fraps so I can show you what I did before the nerf. That makes sense.
I never said I could take on 3 sages/sorcs. I don't think anyone could unless the sorcs in question were not using any control abilities at all.
I will tell you that pre-nerf I have successfully killed a sorc, merc, and sniper guarding a turret in Alderaan through good use of LOS, Interrupts, stuns, and combat stealth.
Believe me, or don't. You've obviously already made your mind up. All I can do is tell you that good players will still be successful with the class. The fact that you think it is worthless just shows your ability.
