IA/Smug are the worst classes to level, have horrible animations (especially operative/scoundrel), are the least iconic of the classes in a game based around force users and even at the "power" they are now, have horrible representation (not basing it around OP's anecdotal evidence take a look at the numbers on different fan-sites).
Nerfing any spec of these classes would be just stupid. There has to be a incentive for people to play IA/Smug. If anything they need a overhaul, just wait until rated BG's and Arena to see these one-trick-ponies fail miserably as they offer no utility.
