Has anybody enjoyed the abyss?
Personally I have no motivation to do abyss, it looks boring and repetitive and is topped off by the horrible collector fight. Plus it takes months worth of mind numbing arena grinding for the resources required to beat it.
However, a lot of people have beaten it. So to those that have, did you enjoy it?
Did you feel it was worth the time and effort to grind units for it? And if given the opportunity to do abyss again for no rewards, but you're given all the revives you need for it, would you do it?
