It's about time to add Coil story mode, isn't it ?

But dw, at some point our gear will make EX fights as easy as how HM are now, you should try it again then.

No amount of echo or gear will make Titan EX or BCoB easier. They all include mechanics that one-shot you if you don't..well..know the mechanics!

Unless you mean wait until lockout is removed and people sell T6-9 more frequently to buy a run and experience the story. In which case that's just terrible to suggest.
