Often there are no groups avaible, and most of time I spend is on looking for a group.
This is a serious problem of many players, I think.
Aren't there any quests that can be done by one Adventurer from level 10 or higher? I didn't see any quest like that.
I think that an Adventure Pack of some (about 10) unconected quests of level 9-14 or 15 of different duration that could be done only in solo mode would be a great thing.
