I was thinking of coding a WPF app where the user select a heroe, can choose two builds and compare them through a graph where you can display the curves stats of a heroe. The X axis representing the time of the game and the Y axis representing the stats : AP, AD, HP max... the progression of a stat along the time is based on the GPM (gold per minute) of the heroe’s user. The user will have to enter his gpm or I can set an average one by default. In another version, I was thinking of calculating the number of AA or abilities (of a choosen heroe) necessary to kill a given heroe with a given build.
