So I've been doing fine mostly soloing with my now 10/1/1 cleric/rogue/fighter, but lately I keep hitting the wall in quest after quest. Today I did Ghola-Fan, spent well over an hour clearing out the whole dungeon only to get nuked by the boss, and then unable to return within the (annoyingly short) 5 minute timer. So, a giant waste of time, though I did at least get an item with a haste clicky.
This is nominally only a level 10 quest as well. I am finding more and more level 9 and 10 quests I cannot do at level 12. This one was especially frustrating not only because of not being able to get back in, but because 99% of the dungeon is easy and then the boss chamber was a complete wipe-out.
As an aside, this "harried" business is beyond annoying.
