You have to collect relics to get the damn exocore it should last longer then 7 fking days I mean seriously can it at least be 45 or 60 days or maybe even you know permanent? that's a lot of griding to get something that last 7 days.
No thanks. The only boss-mode exocore(s) that should even be considered for getting a perm version is Big Dog, and maybe Leopard. :v All other boss exocores are completely unbalanced and thus should never get a perm version. I will agree with getting relics = get a longer lasting exocore, though. Definitely should be a 30 day one from those, since you can get the 7 day one straight out of the box. :v
