Make Wyrm and the upcoming dungeons relevant. Khitai power loot with a little extra for those who get full sets. You have to give the players an incentive to do the new stuff. It is awesome stuff but nobody does it.
Increase the gold reward for the repeatable quest.
Give MoA for the repeatable quests.
Make a new faction for Dragonspine. Give it some decent rank 4 loot. BS needs a STR + healrating cloak. I’m sure that other classes need stuff too.
Make the new Dragonspine raids part one of T5. We don’t need another T3,5 and you guys don’t have the capacity to do both. You can release part two of T5 next year.
Make rank 4 of the new faction required to enter the new raid instance.
Make a new milestones quest for Dragonspine with a tempting price for doing the dungeons over and over and over and over ...
Dragonspine as it is now is a wasted opportunity. Make it shine
