[FONT="Bitter","Open Sans",Helvetica,Arial,sans-serif]Thi[/FONT]s event greatly pissed me off. It started off ok, but as the days went on, it got harder and harder. For example, it took me an average of 180 quests just to get a single Soul Demon guardian. Out of every 200 quests (eg, resetting Unite the Tribes to see if it was a useful guardian...also did similar w/Lots of Rogues, but not every civ has good enough LOS to where you can see the guardian off the bat), I could get 2-3 Emerald Guardians but only 1 Soul Guardian. My worst was w/my Norse; I farmed over 36 hours before my first F'n Undying Soul. I killed about 15 Soul Guardians before I finally got the dang item I needed. By that point, I had almost 3000 Meteroic Iron and 1200 Blackwoods. I had trouble getting the Soul in another civ, but I luckily got it from the Large chest...that was, until they changed the rewards again to junk L40 rare items. Another complaint, is the ~15 vanity items I have but can't apply, because they disappear and aren't applied to my inventory. So I have about 20 invisible vanity items and about 40 sitting in my vaults until I know for sure they're fixed.
Also would be nice to know if this will be extended. I have enough blackwood/iron/emeralds to get about 10 more swords, but the dozens of days worth of farming it'll take to get more souls...it's not worth the effort.
Agree that the reward for killing 10x of each Guardian should've been the item.
