If you want the story experience, just...unsync them? A level 90 tank or healer (or DPS with a little sustain) can solo all of coil with little issue. If you want the coil experience, get a group to do it.

While I'm a fan of the *idea* behind adding engagement to the duller old content, coil isn't dull. And I don't think older raids would improve if the modern Shadowbringers fight templating replaced their original design. Do we need yet another fight where the boss has Generic Raidwide That Comes Once A Minute, or Easily Mitigated Unthreatening Tankbuster? Boss That Teleports To Center And Casts For Ten Seconds? Yet More 8-Person Protean Waves? Okay Guys, For This One We Need Light Parties And Clock Positions?
