All 3 Specs work fine for leveling (mind you healing tree will let you solo harder heroic zones with Khemmy, no matter what tree you go with Sorcs always take ~9 points in lighting first to good to pass up). You get XP in everything you do PvP, Flashpoints (use the group finder for 5 bonus commendations Yippe), questing and Space missions.

All you need to fill in are the first 2-4 categories on the GTN.

For space combat you need space ship part of the correct level for the mission your trying to do. The checks are gear ranks 0, 1 and 3 when levelling. If your trying to do a mission with gear below the ranking listed your find it hard if not impossible.

Its possible you already collected it as you cant tell if you have picked it up or not with out checking codex to see if the datacron entry for it is in there. Press L switch to Codex and look in datacrons is there an entry called "Galactic History 05: Rise of the Infinite Empire" if so you already got it.

Speeders price start at about 8K credits and piloting is under 200 credits I would only buy the pack if you want the extras. I Spent mine on increasing my account backpack size for all characters thats 350 coins for every character your ever make vs ~20K credits per character.

You can see how it works if you go speak to social vendor with a companion out who uses a different armour type to you IE a Sith Inquisitor with Khem Val though the item will have an armour rating and value for both. The armour rating will be 6 for both the PC will only get ~30 armour and Khem Val will get ~120 armour.

If you dont want/care about the set bonus you can use what ever you want. IMO they are poor anyway like +2% more shield points on bladestorm procced shield for a tank spec Guardian basically useless (its 2 small to make a different).

Press L look at what quest is class quest then press M and mouse over class quest it should highlight where to go on the map.

Light side choices make more since in some ways, as such my Sith always ended up more light than dark, unless I pick just for DS or LS points in game. As for Sith VS Jedi it comes down to this IMO Sith have feelings and Jedi are boring lumps of unfeeling stone. As for Light and Dark we never been told what the force is or how it works, all we are told about is belief system. I believe the force don't really care if your light, dark, grey or a rainbow (some groups in Star Wars universe think its coloured) nor do the types of powers used.

If he has no emotions he cant feel fear as that an emotion.

Sorry your Spoiler is wrong it only if the .

Hmm as I remember it, the hunters are a group of criminal citizens of the empire not sith. Anyway the reason you tag the sith acolytes is so the hunters tries to kill them and then get cut into little bits by the siths, ethier the acolytes or some higher up sith for dareing to attack a sith.

This buy make sure you buy the Account Version of the upgrade and not the Charater one. The Account version is a tiny bit more costly (think its about 2.5x the price) but when you going to have 3+ chars that a good buy.

Your sure that it not because your type 2 guardian is in heavy robes where your sent is in medium?

Well like everyone says why do you want to hit stuff any way? The Sorc/Sage has always been useless in Melee even when we did have +melee from willpower.
