I started off the game as a Soldier my first time, mainly because I wasnt sure what to expect and I new a "Tank" wound have a good survile rate...and it did.
My feats where usualy Flurry/Two weapon fighting/Toughness...then of course Weapon Specialization (Lightsaber/ Melee Weapons) if you have extra Feats try Implants...at level 3 you can get a +4 dex implant or a 2 regeneration....helpfull yes?
Attributes
Str-14
Dex-16
Con-14
Wis-14
Int-10
Cha-8
If your not planing of using persuade theres not much use for Charisma. A higher charisma affects you followers slightly in they will keep attacking the target that you tell them to. I didnt find it usfull enuff to justify putting points to it....I dosnt effect prices or genral reactions of NPCs when you first meet them.
Intellegence is good to have if you like having Skills but of your playing a Soldier/Gardian class's its likly that it wont matter much. Soldier/Gardians only get 1 Skill point a level unless there int is 14 I belive...then it goes up to 2! gee wow (you'll have to depend on your other party members to detect mines/disarm.
Dex for Armor Class...you end up in robes generaly at the end. Also if you want a high AC make a Scoundral/Gardian and dont level your scoundral passed 7. He gets a +4-24 on sneek attacks (this also meens when the monster is stunned) and a +4 to AC (I think it was) cross that with Dueling (+3AC at max) and give him Critical strike (with the right crystals in your saber) and you'll destroy the bad guys =)
Str for beating things into the ground....if you plan on using a pistol wielding Jedi and no light saber then dont bother with this! lol yeah right
Con....well more hit points!! if your a Solier/Gardian you really dont need this too high...with a 14 I usualy ended up with 275HPs or around there.
Wis is for your force points...more Force meens more Death and destruction! BWA HA HA HA.....ha? If your going to rely on force then pump this up.....oh and its good for Will Saves, so does Cha! but who cares couse your beating them into the ground hehe.
Force Powers I always stayed will Heal and Force Push/whirl/wave and Stun/Disable Droid.......Force Suppression/breach Lighsaber Through and Mind Affect are also usfull.
Okay I think Iv gone on enuff..
Oh! you can make way more coin if your Dark....I came out of Teris with 10000 credits...you can still be nice to people, Just dont give them any coin..and threten with nessesary or when it suits you

Being light or dark affects how much Force Points are used when you use a Force Power...So just becase your good dosnt meen you cant have Force Lightning, it just meens it going to cost you more.
There Im done
