I was running some solo instances with a guildie and the last chest only gave one goodie box. The gear from the goodie box inst even trade able with the person you cleared the instance with. Any way to give a box to each player and or make the gear trade able with the other person with out turning it into SLR spam?
They are called "Advanced Solo" for a reason. You can have up to one other group member with you, be it merc or another player. They are meant for up to two. I don't think two chests should drop, but I do think you should be able to share trade the loot with the other person in the group if they were there for the kills with you.
Yeah, Dracur Prime solo in Skyshrine was the same way on the boss drop, but at least the mission rewarded both players. Also, given the way loot works in these zones, is the lockout timer even necessary?
