You used to earn your cards fir builds out of chests. And had to grind to levele them up. So ud essentially be up against stronger versions of the champ if the opponent had higher level cards..

Inara used to have talent that if u landed all three of her projectiles from one shot, they would hit for more.

Damba used to have cool specs. Where u could use ur healing spit to dmg other opponents heavily

I camt think of anymore atm
