Just a quick update, it seems the 70% tt return problem is finally fixed. I did quite a few runs in solo mode and got the same return as out in the wild. Can't be sure about team mode, cuz simply haven't tested it. Also haven't touched the Golden key so can't talk about that. What about UL item drops, got 2 daggers (songkra and aakas fire) maybe was lucky but at least it shows the chances in instances are higher by a magnitude (have slain gazillion mobs on Ark but never seen any UL weapon drops outside instances).
