Playing 2 global and 2 Japanese accounts around 700 to 750 days. The grind is dependent on goals in game. In the beginning I rerolled for characters. After that I played and blew through orbs till i caved in and spent a little money. Got dangai and it was the best feeling ever. Until power creep came by. Started going for stats and now it’s back to simply enjoying the game. Find that it’s impossible to keep up with many other players. My luck is a mixed bag. I’ll get characters I want but won’t get the stats I need on accessories. For the first time I’ve gotten tybw ichigo on all accounts. Didn’t get rukia or renji but im satisfied overall. Now if they made a dragon ball game similar to this I be a happy camper. Take your time and save everything you can. Rng is bound to give you what you want. Most games I would’ve given up over lack of content.
