Busy Father, looking for advice

Hey guys, I know this is the most common question, but I'm in need of some help and asking my wife or toddler on this matter isn't getting me anywhere. I've got a 22 gunslinger and a 24 Shadow, both on Republic. I was a druid that respeced 200 times in wow, and I loved every tree. I was also a shaman and paladin, so I liked hybrid but always had a little dps envy. Shadow seemed to be right up my alley and I really like the feel of the defense tree. Infiltration seems pretty basic which is probably a little downgrade for me. Balance feels great, a challenge that is fun with lots of damage and aoe with some range. I think it compares mostly to the enhance shaman or frost dk if we are comparing. So 2/3 are great for me on that, but I was the last to come over to SWTOR , from my friends. My brother and another friend decided to take on tank roles since I was undecided on playing (yeah I did the annual pass......), so now my brother is a guardian level 46 and the other guy has stalled out his vanguard at 40, and is picking up sage and likes it.

The slinger, I like it quite a bit. Great range and fun to take people down fast. I like all three trees, and I don't mind the cover mechanic. Getting that damage reduction for taking cover is great on top of the dampers that we get in the talent tree. We plan on doing mostly PvP and probably some instances, but doubtful we will ever raid, and if we did it wouldn't be much.

I'm wanting to focus on one at this point, I thought I would level both at the same time, but I was reading about the legacy perks so I thought I should get the full experience and focus on one character.

Question: From what I've described above, tell me if you relate to my previous game experiences, and give me your honest feedback. WOULD A GUY LIKE ME EVER BE SATISFIED WITH A PURE DPS CLASS? Druid/Shaman were my bread and butter in WoW. The difference being that Shadow Consular isn't ranged, even with some range in tree.

OR DO I STAY WITH 2 AT THE SAME TIME?

EDIT: I chose to right this in the smuggler forum, because I felt that the most regret would come from choosing a pure dps as your first. I'm in no way hating, I think the Smingler is great, and I'm going smingler to 50 as of now, just wanted to hear smuggler's opinions over shadow opinions if you know what I mean.

What exact specs did you enjoy most? If you were Feral/Resto or Resto/Enhance than Scoundrel is probably closest. If you prefer balance/resto or resto/elemental than Sage is the way to go. If you want to heal and do ranged, but don't like casting so much than you could try out a Commando which plays more like a hunter but with the ability to spec for heals.

I suggest these because they have the ability to heal, which may be a commodity in a group of people that have all gone tanky. If you're looking for pure damage than you have even more options depending on the type of damage you prefer.
