Why do boots increase movement speed of champions who can't use them, like Janna or Hecarim?

How can there be two of the same champ in the same game but not the same side?

Well...

Summoner's Rift and the other Battlegrounds have a high density of magic. Because of this, it is easier for summoner magic to exist there. Summoners create semi-clones of the champion, which keep some personality (taunts, jokes) but not all of it. Extreme hatred or other quirks will survive the cloning process.

Why do champions deal the same and do the same damage even if they are wounded?

The reason that champions always deal the same amount of damage and never suffer battle fatigue is because it is not their true body. Their true body is stored in the nexus. The summoned body containing the champions memories personality and abilites has the normal limitations of the body removed by the magic and because the summoner is controlling the body it dosen't feel the body's pain and can push it to use it's full ability even at the verge of death.

However there's another theory going arround the institute of war , saying that such an amount of CC would annoy summoners so much that they may lose control of their powers and end up destroying half valoran and thats why the council doesn't allow it .This is only a rumor though

why is kennen able to turn into lightning and not get hurt , but a xerath ultimate is still able to damage him?

Kennen when using Lightning Rush actually becomes a formless mass of pure energy. Unlike physical beings, beings of pure energy experience other energies as though they are solid objects. Because of that, Kennen does not get shocked by Xerath's ultimate, rather he is being pummeled to the ground by it. To Kennen in his lightning form, each hit from Xerath's feel like a fist smashing down onto him.



What are patches? Why do champions get buffed and nerfed every few weeks?

Patches are a type of bandage that the summoners put on the champs to either increase or decrease their performance respectivly. They do this to keep things interesting for the spectators.

So where is the old, pink, big nosed shop keeper and why was he taken out of the league?

That old shopkeeper is actually part of a race of pink humanoid pigs that have been warring with the Yordle. Realizing that the shopkeeper was secretly funneling the gold he earned to his own race's war efforts, a group of Yordle manhunters were dispatched to slay him one night.
