w/Kaliyo I kill faster but have to stop after most fights to heal up. w/Lokin I take a bit longer to kill but I can move right from one pack to another. w/Kaliyo I can take a solo gold mobs but she typically dies, and it seems as if I barely pull it off. w/Lokin I can fight a gold forever without dying, and have even taken a gold + silver at the same time (Although it was close).

I am only 40, but I don't get anything between now and 50 that changes anything. I typically open: Stealth > Acid Blade > Hidden Strike > Shiv, Backstab (Since they are still not up) + Adrenal At this point it changes based on situation. If the are already low, I skip Dart, and just spam lacerate/shiv/backstab till they die. I agree that it is really priority based more than rotation because of procs and such, but my priority of attacks is: Keep Adrenal & Acid Blade Up Hidden Strike (If Stealthed) Backstab (If < 75 energy) Shiv (If not at 2 tactical advantage) Backstab (If > 75 Energy) Rifle Shot (If < 60 Energy) Corrosive Dart (If Target > 40% HP) Lacerate (If I have Tactical Advantage) Shiv Overload Shot (If > 85 Energy) Rifle Shot

I really think that Operatives are designed around the fact that they win 1v1 if they catch you while they are stealthed with full cooldowns. I personally think your best bet to try is to use your break CC cooldown immidiately, and pop your 50% DR ability. They can still re-stun you, but you would already have the DR up. They could always just Cloaking Screen and wait out your DR though. Having played both sides of this, I think you just lose if you get caught by one stealthed. Talented Hidden Strike is just THAT strong.

I currently have a level 35 Imperial Agent (Operative), and he is a lot of fun, but I want to level something else with light side choices. The irony of being a light side Sith and seeing how it plays out sounds really cool to me right now. Also being heavy armor with a lightsaber seems cool.

I really like the idea of being a heavy armor wearing DPSer. Can Juggernauts keep up in DPS with Mauraders, or do I just need to spec Marauder if I want to be competitive?

Yeah, re-doing the quests like that seems to be the best way to get the most out of the content, but I have always had a hard-time re-playing RPGs and doing the exact same quests as a different 'character'. I like creating different character concepts, but when the story is 90% the same I get bored quickly. I wish they would do something with the legacy system that made additional characters level at just the right speed that you can only do class quests. Whelp, back to more Hutt Ball...

So I am trying to level multiple characters, but since every character has to go through the exact same planets, I am trying to avoid doing any side quests on all but one character. The problem is that just doing class quests does not nearly get you enough experience to move on to the next planet. Is anyone else in the same boat, and how are you making up for it? Flashpoints, Warzones, Space Combat? Trying to find the most fun way to do it, and I am really enjoying Space Combat, but they don't give much XP and seem to get grindy very quickly.

I am personally of the opinion that you should be able to change ACs, let alone just respec within one AC. Here is why: This game is about STORY; fully narrated, engrossing STORY. It is bad enough that there are so many shared questing areas between classes/factions that all of the side quests get repeated, but I am personally willing to deal with it to experience the class specific STORY. Once you reach max level, there is only so much content, but one of the things that many people enjoy is experimenting with different specs. Personally I am leveling a Power Tech currently, but I already kind of want to try Mercenary, just to see how it is. You know what I am not doing though; playing through the EXACT SAME STORY all the way to 50 just to try it. I can't think many people will want to do this. It would be different if the class specific story branched off completely at the point where you choose your AC. Since it doesn't, you are forced to pretty much do the exact same thing for 50 levels just to try out the other AC, and that is just ridiculous. You should be able to re-spec (For a reasonable cost), including changing your AC...
