If I solo a 3-man adventure, I really wish my loot can be tripled. If 2 people do a 3-man adv, each person gets 1.5x loot. At the moment, I can still get 3x loot with my adv, but in a much trouble way. I can swap or sell the lootspots, then use that money to buy the same lootspots from other players.
The lootspot thing is not supported by BB. It's risky and trouble, and of course, have to wait for someone to do with. Sometimes, I do advs till late to finish it before my premium ends, but no one else is around to buy or sell lootspots, not even my guild mates are on to share with them.
If I can get all the loot, I don't need to depend on the lootspot thing. I won't be afraid if some guys ruin my blocking plan even though I instruct them already. I'll also not be bothered by someone who are AFK for hours, then demand a refund. I can do and finish at any time I want.
