I'm in agreement with the OP. I've been playing a Gunslinger since release day, and I've actually had to step away from the class on multiple occasions out of sheer frustration. The cover system is one of the worst experiences I've had with a ranged class in nearly 8 years, and while it's functional, the fact that I can plant myself down say, 10-15 feet in front of an elite mob, order my companion to attack it or pull it myself, and suddenly be unable to see the target that I intentionally placed in front of me without obstruction is ridiculous. One of our primary nukes, "Aimed Shot" cannot be used in 90% of environmental cover, regardless of the placement of the mob. I roll into a spot, charged blast, and start to cast AS, and "Unable to See Target" (while it's directly on the other side of said cover) causes me to have to deselect my target, plant myself in shielded cover in the open, and start fighting all over again. This is provided that my cover triggers prior to my twitch reselection of the target, otherwise I roll DIRECTLY BACK TO THE SAME BUGGED COVER AS BEFORE. That and the fact that I get to blow my GCD resetting cover each and every time just makes me not want to play the class; it's one thing to be forced into a group for heroics, it's entirely different to die repeatedly to an unresponsive UI or a core feature of your class and be unable to solo normal quests without extreme workarounds.
