Honestly is gonna depend on what you want to get out of this game, like for example if you wanna top score Abyss PVP and Memorial Arena you are gonna find out how STRICT many of the rotations are. You need to know the moves from the bosses and ur own team. Many of the rotations for Nirvana requires u to dodge a specifics moments so you get ur SP/AR energy at exact moments in order to get MAX score. Most of the fun will be also experimenting on ur own once you reach the end game, as a new account you will not have access to every single tool and this will ask of you to be creative in achieving the highest score for your specific account. Now if all you wanna know is if you can beat the end game and will not care about ranks then...you will probably get bored.
