I currently have the 3 star for fabian and I have the means to go for the 4 star but not even close for the 5 star. The only advantage the 4 star has is 1000 hp and crit dmg which isn't useful on him. Also I will probably never will be able to afford a soul in the market even if I gotten the 4 star and tried to get a 5 star later. Should I just stop and save resources for the future or should I regardless of this pursue the 4 star?
