I tried to run the new quest Creeping Death tonight on Lamannia but I had to give up. This was on Epic Normal (so Level 31 quest), and I was on a Level 30 (boosted in the Dojo from Level 28 on Live) Bard THF Warchanter/Barbarian. This is a first life character so doesn't have all the bells and whistles, and my gear is a mix of named items (Cleaver is my main weapon) and other drops.
First of all, the Legendary Kobolds and Oozes were a royal pain. Annoying and not fun at all. The oozes, in particular, weren't doing much damage to me, but were certainly destroying my weapons one after another. What epic-level weapon does one use against oozes? I have Muckbane in my vault, but that doesn't seem appropriate.
Second, where I had to give up was against the Horned Devil Invader protecting the second rune. I was literally doing no damage to him at all. He has some kind of legendary ward buff that prevents damage and, well - it is certainly effective. So what kind of weapon does one use against him? After beating against him for a while to no avail, I gave up and recalled.
So, I guess my concern is this: Are first life characters going to be able to complete the new Legendary quests on their way to Level 30? My impression is that much of the Lamannia feedback has been from players running Epic Elite and finding everything too easy. But that wasn't my experience -- the quest wasn't exactly difficult (except for the one time I accidentally ran into the insta-death red gelatinous cube, I could survive most fights just fine), but it was certainly frustrating.
