Maybe Nutaku's Aigis main competition was the DMMver and if dev was getting even twice as much profit for the same amount of effort, it would make sense for them to stop trying. Unfortunately, Japanserver of game will always make a lot more money because of willingness of player to spend. I see this as something that was long time coming, although I am surprised it ended as soon as it did. All online game will end, you only pay if you feel you are getting your entertainment's worth. No one can complain about their favorite band ending concert tour, it is band's decision. If you enjoy going to concerts, you pay for that concert.

If u enjoy Aigis for its gameplay, it is strongly recommended to join me and try to at least start on DMM and see how it goes. Every time there was new reason to sign up in DMM whether in 2015 or 2016 u hear tales of how player caught up to their Nutaku progress in a very shorter amount of time because the game over there is much further on. I more understand that while it was likely dev Tea's decision to stop supporting English version, probably their reasons for doing so is related to business and DMMver is at much less risk of stopping because the paying userbase is there and very guaranteed.

Maybe Nutaku could have handled things better but I think it was over when Nordland said dev Tea wanted to continue handling the service about 1year ago.
