Fortunately for the Coils, the only things they deal with lore wise are the wrap up for the loose ends of 1.0 as well as fleshing out Alisaie's respect for the WoL more. I think they can be left alone, in favor of the dev team working on what's new. They'll always be there, and while newbies may feel that they're missing out, it's simple enough to put a PF and have a couple level 80s bulldoze them for you.
