Playing on PTS there are no groups, but I decided to go heal spec anyway.
Soloing is pretty straightforward although you do need to be at level for the quests to cope well.
Rather than sticking with Qyzen, I find Tharan the most versatile, especially dealing with golds as Holiday's interupts help enormously. For general ploughing I prefer the Leiutenant to Qyzen, although when DPS alone isn't enough I pop out Tharan again. Haven't had Nadia long enough to really work her out.
Oh yes and I keep EMP switched off and make careful use of force lift to manage incoming damage.
Currently level 45 having yet to group with anyone :-s
