Give the interface a personality

So for example a voice similar to in game when you do such things as trying to buy a skin without enough RP. A cool/changeable/buyable/earned voice to let us know in maybe a troll tone that "we need more RP". Makes the game more immersive. Now it just tells me YOU NEED more RP in a text box. Make the interface move like it is breathing. Would be very cool if it felt like you were dealing with a manifestation of something you are playing.

Here's another one. Create tabs for champion setup. I won all champions and it would be great if I could have user defined tabs for say Common bans, ADC, SUP, TOP, BOTTOM, MID...

There are many more things you could improve in the game to make it more addicting, fun, and easy to play.
