By clarity i mean that there are many things unexplained that impact the game.
Here are some examples:
* What exactly is spell damage and what types of abilities does it work on?
* What item will these two unequiped components create?
* What is the stun duration on Lissandra?
* What is the mana burn/shield number on Kassadin?
* What are the base stats of champions?
All of these and other unmentioned ones should be available in the game.
