Sadly already finished with Cosmic Exploration

I think a lot of the 100 penta melded crafters are opting to get gold on the A ranks, then swap back down to the less intense B ranks for grinding because you can just smack macros for those. (Even then, you better pay attention on what the durability and quality requirements are.)

Faster to spam B rank missions for I, II, III research points even as a pentamelded crafter.

A rank missions for IV research points, but I'll only touch one or two of the missions out of the bunch.
