Well now that next coil will be coming out with next patch they should do something to get most of the ppl done with first coil at least imo. There are a lot of players who haven't done it (just for your reference I have done it quite some time ago with 5% echo because I didn't even try it much before they made it with echo and made my way up to t9) and SE rly needs to catch them up to speed. Because of course you can view coil as optional end game stuff. But it actually is quite vital to the story line in my opinion. And this is "old" content that we are talking about here. Especially once the patch 2.4 hits. None of the loots or rewards from that will be anything special so I really wouldn't mind that most average and bellow average players complete it.
