I have no desire to play the challenges. I was burnt out on Crystal Cove, and I have never even visited Mabar. Considering both of those are free, I will not purchase the challenge pack. Like posted above, they seem like minigames and not real quests.
Also, I do not wish to deal with even more ingredients clogging up my inventory. I already have 2 or 3 ingredient bags on all my characters and I'm at the limit with Scrolls, Seals, Shards and Cannith Crafting items as is. Imagine my annoyance first walking into the U11 explorable areas, as I cannot even choose to leave that junk on the ground.
During Crystal Cove it was impossible to pry people away from the event to do other raids and epics. Somewhat understandable due to limited time scale of the event. However, now my guild is entirely worthless for actual questing as they just want to do challenges for the quickest tokens. Unfortunately, there's no fixed and timed end for challenges. Considering finding somewhere else to play if the guild is going to be this consistently lame.
30 tokens for a Yellow slot in normal game play is far too tedious, especially if you swap gear (tanks especially).
Epic VoN4 and Spies in the House need to reward a full dungeon token for the trouble, but real epics all around need a boost to match the epic token rate you can achieve via challenges.
P.S. I had someone with that stupid Elemental Rapier with the Slicing Winds effect blow out my dancing ball crowd control in an epic. Why go through the effort to get a weapon that just is a griefing nuisance?
