I wanted to take a few minutes and congratulate/thank the people responsible for this event. I enjoyed it a great deal. Here are my "notes" with follow-up suggestions.
Foreword: I rarely play epic and don't care much about it so any of this that is not applicable or voided by epic - I don't care.
Overall: B+
I enjoyed it a lot, but it was not quite perfect.
Foremost, it was fun. It was a bit grindy, but it was a varied grind that required at least half a brain cell. Loved the kobolds.
I really like the loot. I think earthen guard is over-powered for a level 4 item, but it's not a "breaker", and the rest of the stuff that I liked primarily moved things to different slots and/or replaced other things.
For instance - instead of having to grind the quest chains for a ml5 mod fort item I was able to craft it = win! Also, was able to craft a ml9 heavy fort to replace my nightforge so I have my necklace open for silver flame from level 9-11 still, so I got nothing new, but rather a better allocation for things I want.
Suggestion: rather than always trying to one-up old loot, doing things like this is much more rewarding and less frustrating. By having more choices for where we want to locate certain effects on our characters we have more ability to acquire, more use once acquired, and less feeling of loss when we replace it with newer loot.
