So I played a shadow most of beta then tried a sentinel and finally a trooper (only to about level 8). I have to say more then other MMOs i liked staying at range but I cant find any good info on what the Sage gets at 10 when picking the advanced class. I know they get a passive to bump force to like 500 but do they get a spam-able ability to let them stay at range?? Project and force throw both have CDs so I assume I get a low cost no CD force move "filler" ability. Anyone that played a sage that can confirm this??
You don't get one you can spam, no. You keep the 30-yd instant stun, the castable Force Lift, and the knockback. Some skill trees enhance these CCs-- making Force Lift instant cast, reducing the CC on the 30-yd instant stun, removing the CD on TK Throw. TK Throw is a snare, so while you are rooted while casting, you can buy yourself some extra time for a teammate to peel or for one of your other CCs to come up. Later on you get Force Speed on a 30 sec CD.
I can only speak about my experience up to level 18ish and specced as balance, but in PVP there was almost no situation when I was unable to keep a melee at a safe distance.
There is a chart floating around with all the CCs for every class, I'll try to find it.
