Hey everyone I was doing some math up to see how many lvl one common characters it would take to reach the max level in game and I'd like to know your thoughts or if I messed up on my calculations lol but if you took a lvl 1 character and raised it to the max it would take 

lvl 7 takes six lvl 6 = 9250 lvl 1

lvl 6 takes fiv lvl 5 = 1320 lvl 1

lvl 5 takes four lvl 4 = 220 lvl 1

lvl 4 takes three lvl 3 = 24 lvl 1

lvl 3 takes two lvl 2 = 6 lvl 1

lvl 2 takes one lvl 1 = 2 lvl 1

If this is right it's really advised to use up any of the uncommon and higher to just max one character out. Granted this is not impossible to use purely common characters but that would take a long time to get them all and lvl them up accordingly. 

Again let me know your thoughts or if I'm way off on what I figured up.
