I almost completed the star chart and just playing the game without a real purpose. I just do it to see what comes next. I feel like mastery rank system is weird since i have to constantly change weapons after they get max level. Because of that reason I never get strong. When I finally get a weapon to level 30 and can use nice mods, I have to change the weapon. The story feels bad and disjointed. Missions repeat themselves after like 30 hours. What to do to have fun in this game? I already played around 70 hours but I can not play it anymore. Does someone know what I should do and tell me the purpose of the game?
