I am one of the biggest advocates for stealth and CC’s. Loved them leveling my Sawbones and Shadow, absolutely loathed leveling my trooper anytime I had to solo an area (the reason she is stuck on Belsavis at level 41). However, on my Sentinel after buying the faster quick travel, I do not mind the lack of stealth and CC’s. I run around them and if I happen to pull something, I just kill it. Only down side is I am always overleveled.
I loved the agent story, but I found the ending kind of meh. Still really glad I played it first.
