I am definitely not going to leave my JP account for NA. The horrendous localization issues aside, I have invested far too much time and money (more than I’d like to admit…) in rolling and raising all my waifu servants. Considering how much time and luck is needed to farm up ascension and skill items, that all my friends play on JP, and that I can read moonrunes anyway, I can’t think of a single reason to throw that away for NA. The sole fact that I pulled Melt after almost 2 years of waiting and a loooot of salt with failed rolls is already enough reason to not give it up.
That said, I get why some people would want to switch. But I figure the more you’ve played, the less likely you are to want to give it up, so it makes sense that no one on the subreddit talks of it because chances are you only post on there if you’re a veteran or a NA starter. I know some people playing both atm, but I don’t think anyone intends to juggle both long term or switch completely, and then I know people who quit the JP awhile ago and are now coming back because of NA.
