I think the box I got my kit from was a white standard quality box. It did come with a permium credit box so I think my treasure hunting mission did crit (as it would normally only gives me one box). I've run maybe 40 treasure hunting missions for tier 6 lockboxes and this is the first battlelords' drop I've had, so they are quite rare.

I had been buying the battlelords' gear from the GTM for a while but just received some Battlelord's greaves from an ancient premium mission box which I got from a standard treasure hunting mission (I've got treasure hunting 400). Just need the armguards and saber to complete the battlelords' look now...

AFAIK when right-clicking it uses whatever ability is in position 1 on your main toolbar (assigned to number 1 by default). That way you can have whatever attack you start with used when you right click an enemy (not sure if it works with heals if right-clicking friendlies and a heal in slot 1?)

I'm too busy leveling at the moment. I'm hoarding all the purples and schematics I loot (got 1 bay in my cargohold full already) so will start to sell it when I need the money and/or when I actually know what to charge for things - not having anything equivalent to base my pricing off makes it hard (and not knowing how easy it is to earn creds at 50 as a baseline of how much a credit is worth to a lvl50).

All the flashpoints I've done we've had no issues getting healers (never had to ask for healers either - there's always at least 1 replying to the first LFG message)- the biggest gap is tanks at the moment, so I'm having to tank in my DPS Guardian. I'm level 41 now and I've seen more than enough heal capable classes around my level (~30% if I had to guess).

I went and did CoS (a level 8 or 9 heroic) with a level 8 friend on my 41 guardian and still got the same social points as if I'd been there at the correct level, which makes sense as social points have nothing to do with character level.
