All good feedback and thank you for it!
Current thinking on iteration is to modify the requirements of the cover quest. I.E. "Do X of Y" and some of the objectives within the WQ's themselves.
Going to be modifying the uptime of these. They will be more rare and short duration so that they feel more special when they are up and itemization should make them lucrative and appealing.
Exploring the option of having these available to do on alts who are still leveling up in the Broken Isles. Would be a way to breakup the level up experience and hearken back to that aspect of the pre-launch events that folks enjoyed.
Misc. behind the scenes tweaks and tuning happening as well.
The real itemization/reward pass hasn't occurred yet (waiting for this feedback round to settle out) so that will help once it is done. :)
Thanks again for the feedback and look forward to more after some of the updates above make it out to PTR in the coming weeks.
