How do i ''safely'' open lockboxes?

[Arise]

Solution is simple. Invite rogue to group and youll see items he looted from box.

That only works if there is just 1 item in the box. If there is more than 1 item the rogue can only loot 1 and leave the rest in to loot later.

The solution is the not give a shit about rogues like any sane person would, and use skeleton keys.

Solution is simple. Invite rogue to group and youll see items he looted from box.

That is just a false security since as a Rogue I don't have to take out all form the box. Say for example that 2 greens and a blue drops, I just loot the green and trade over, leave party and THEN loot the blue

Hey if your on alliance side ill be willing to open boxes for you in group! name is Paperkut
And as to the thorium boxes, they sometimes contain a lvl 27ish? grey item indeed, im pretty sure that player screwed you over, in the beginning tho the items in the boxes were bugged i must say, some empty and some with like 4 greens in them but that got fixed quite fast. If you have green boxes they ALWAYS have 1 green item afaik but the shitty grey boxes only contain trash usually not even poison materials like they should

also no rogues want to party with me they all decline invitations

If they won't accept a simple party invite, they are hiding something & you are just setting yourself up to be scammed.
