Was forced to switch servers because Imps were so bad on my old one I swear I got trolled by my own team in every WZ. They actually made the alliance look good they were so bad. Moved to a new server but having trouble picking a character. Last one was a 50 assassin so I dont really want to do the same story over again. But the main problem I see with Operative is you have no DPS spec and will be forced to only heal when you hit 50. But from what I read on the official forums the same is true for Sorcerer/Sage as they are bottom feeders when it comes to DPS as well compared to Snipers, Maras, Juggs, Powertechs...well every other class. Having stealth was awesome on my Sin as it let me get quests done much faster especially once I hit 50 and started dailies.
Between Sorcerer and Operative who wins when it comes to the following:
Ease of leveling
Soloing Elite Quests
Easy mode healing.....without addons or even mouseover macros I want the most faceroll healing class possible.
PvP at all levels
Better of the 2 DPS trees because I need to level somehow and I cant heal mobs to death.....OPs have been below horrible since like March so they HAVE to be getting buffs soon.
