I hate to say it but it sounds like the Dev Team's focus is a bit misguided. So long as we don't lag wipe on the dragons so we can actually get signets I don't care if lich dust or vamp vangs aren't dropping at the top tier because I can buy them with motes. There's nothing else for us to really spend them on anyway without a new tier to upgrade to.
So long as Mabar is actually playable I'm sure the community doesn't care if mummies come out of the ground funny or moonwalk or electric slide. Top priority should be lag issues.
