I think I was playing an unfinished translation version of the game, i reached to the fourth fort and everything suddendly was in japanese. ahre
I hope that is the case, will change the save to this new download of the game. The game just started getting interesting and i don't want to look what kanji means what with the amount of textwalls moonlabel does (textwalls i love, i've seen games way worse).
Playing right now with Mary Sonia Ceci Jio Stacy in that formation order, they all are very op and balance each other extremly good, made the 3 forth and (zone of level 28 i believe) in level 22/23 in Eclipse difficulty which i hadn't found too challenging also killed number 82 in level 21/22.
I like rotate characters so i play with everyone, but its hard make good formations with buffs, healing and specially type damage balance. If anyone is having this problem, then the solution is buying all healing items so you can play more freely rather than always having a specified healer role. A good thing and maybe the reason because is not that hard, is that the game has very little all attacks at least in this first stage of the game, but that helps make your formation more freely and varied.
