I'm glad that there aren't more Snipers/Gunslingers, actually. They absolutely rape when played well. As you level you get a number of talents that significantly reduce your "cast time" or actually make your attacks instant, so popping in and out of cover isn't really an issue. On top of that, you can automatically gain 3 charges of damage absorb every time you gain cover, and then another 2 charges when you leave cover.
If I'm fighting a melee, I can jump in and out of cover on corners, especially on Huttball with all the ramps. You have a free Blink basically, whenever you want, as long as you're not retarded and put yourself in good positions, which is hard not to do with 35 yds of range on your attacks.
If I'm fighting a ranged, I have an instant 35 yd range 4 second lockout on short CD, melee stun, ranged stun, ranged knockback, and melee range knockback. I can drop into cover, dump an uninterruptible 5-10k in ~2 seconds, and jump in and out of cover as I need more defensive charges. I essentially have that Sorc bubble on demand. All the time.
I'm good with the cover mechanic. It IS buggy, but it's buggy in my favor. And because there are so few people playing my class, much less GOOD people playing my class, I don't see it being changed.
If you don't want to use the cover mechanic, the Dirty Fighting/Whatever the Imperial equivalent is, relies on cover absolutely 0% of the time. It has ranged slows on short CD's and can actually do a fuckton of damage.
Either way, class is boss. I love it.
Operatives/Scoundrels are also really, really good at 50. If they get an opener on you, and you don't have your "trinket" up, you're dead.
