nta, but blightkings are a treasure of a kit, every model has its own neat elements and peculiarities from the type of armor, or absence thereof, to design of the helmet and equipment or mutations.
To lose this still brilliant and perfectly functional kit in favour of one that may have less variety in designs would be a disgrace.
Best case scenario the blightkings in darkwaters are not a replacement of the normal multipart kit and just an ETB kit exclusive to that box, unlike perhaps other units that might see both a presence in that boxset as well as a follow-up multipart kit, like pestigors or the alleged bloodreavers and bloodwarriors equivalents for nurgle.
