The problem with getting dd is there are soooooo many dds why pick a dd without delve weapon When there are many dozens dd with delve weapon answering your shout?

Dont want to play white mage? Why should the person with rank 15 delve weApon play white mage for you?

There are buyables better then delve weapon such as senbaak nagan or razorfury. The best thing to
Do even when your dd is Max out is to get one support job for now or future events.
