I'm biased as I'm a Gunslinger (And I do have CC, slice droid) but shouldn't the pure DPS classes be the only ones with CC? After all, we should be absolutely NEEDED for something.
Every class in this game is packed with utility, you guys are the only ones that get "bloodlust" style group wide buffs. Every group at 50 will be looking to score a Gunslinger and/or Sentinel. In fact, unless we get a "sated" style debuff then people will prob fill up all their DPS slots with the two classes. The healers can CC, so why bring a Scoundrel?
