They have created different modes for primal fights, I wonder why they don't consider taking that route.

Coil can work like, they release the (extreme mode) first, then come 2.2 they release the (story mode) version of it, but at least keeping the option to do that harder version of coil and maybe omit some loot between the two.

In the current coil you can get the body, weapon and legs, but in story mode those pieces of loot are not obtainable unless you do the original version of coil.
