Yeah, Shadow is sorta different with a 10 meter interrupt and Force Speed.
I would say different because of force speed, force breech and project (being somewhat range attacks) because shadows can move out of AOE and still maintain two of their more powerful attacks.
Jarg never really struck me as melee-unfriendly. The Fabricator droid hates on them more, what with those explosive charges.
Where are you standing for that? About the only thing I worry about in that fight is the one stun droid and the tank losing aggro for a second and it moving so I am standing in the fire when the person firing it forgets to count it down. I've been hit more times with explosive charges with my healer than I have on mDPS.
