Making a new DRK would make DRK better. They aren't doing that though.

DRK tidbit from the recent LL does state:

The recast of Delirium will be changed to 60 seconds and roughly three weaponskills can be executed during its duration. Additionally, the range of Plunge will be increased by 5 yalms, and a new single-target defensive buff separate from The Blackest Night will be added.

Which what concerns me is the bolded. Which means outside of GNB having their full Renzokuken combo all Tanks are getting their burst phases nerfed from 5 attacks to 3.

In addition the only real thing DRK's are getting is a Salted Earth attack, a new AoE darkside attack and TBN for a party member separate from TBN itself. And big concerns like Living Dead are promptly ignored.
