Back in 2009 this was acceptable we had a lot more player who needed items from those.
Nowadays No one really needs because they already have or really don't need.

I see 2 things happening to make those fights less hard. Trusts Or Uncapped.
I would love to do some of those Fights again. But shouting for a party to do a BCNM 30 or 60 can be an hassle.

Also Some ENM takes a week to recover which is ludicrous. is it possible to change that to 1 day Vanadiel time or even 1 week vanadiel time?

Make BCNM Great again.
