I played in the beginning back before there were major changes to the trees, and my level 50 Focus speced Jedi Guardian is in need of setting up all his skills again. Are there any good level 50 specs? All I'm finding is level 55.
Look on Youtube for SWTORDominance; he has a number of videos up that give builds for the various classes and specializations. The builds all go up to 55, but he presents them as a level-by-level plan (i.e., step by step choices), although within a given level in your primary tree you can juggle points arount if a particular item suits your play to get earlier. I've been using his builds for a while, and they're working pretty well for me, although I don't have anyone over 34 (or off Alderaan) yet -- except for the Operative who just hit Tatooine (and level 28) yesterday, they're all 30-34 and on or headed to Alderaan.
I still wish that weapon range hadn't been sacrificed on the altar of Game Balance in SWTOR; it feels
wrong to have a Sniper who has a special ability to give all of her ranged attacks an extra
five meters of range, giving her longest-ranged attacks a range of (@whee)
thirty-five meters. At that range, with a scoped sniper rifle, she should be able to pick which
freckle she hits on her target. It all seems kind of lame after my AR/NRG Blaster that I tricked out for "reach out and touch someone" -- with Boost Range, she could drop an LRM into a spawn from more than five times as far away as my Sniper can in SWTOR (and her Snipe could do almost as well). Hell, my Blaster could uncork Full Auto with Boost Range up and cover a cone twice as deep as the Sniper's best single-target range -- and the 'spray-and-pray' cone attack Agents get only has a 15-meter range. And that must be a
really heavy flash grenade if my Operative can only throw it ten meters.
