As we all know,our hero's attributes will stuck at lvl 100.
After level 100,our hero will be the same as lvl 100 even we reach level 150 or 200.Only thing changes at ranking at "The greatest heroes".
So my suggestion is that after lvl 100,for each level we gain,automaticly +x Fighting strength can be added to our hero.
By this way we can use our hero better at defence or attack.
Thank you for your reading.
Have a nice game.
