this is just a idea i have absolutely no idea if it could be implemented

well i was thinking of a way to make the game better for people who keep coming back to play it so i cam up with upgrades  as in after every 25 times you play as a demigod you will get  to upgrade some of his stats  like get to increase hp on regulus or increase mana on erebus or movement speed on rook

but there would be things each demi couldn't upgrade like ub couldn't upgrade his speed or attack speed   ere couldn't up grade his hp regen same with sedna

so each demis best thing  can't be upgraded  this would also make it more challengeing and more fun for the players who play regulary would also make itless boring and repeatertive
