Why are new players pretty much told to start League on "normal cast"

It isn't even normal cast because a vast majority use quickcast w/ indicator.

I really don't see why in the tutorial, it does not open up settings and point out the three different types of casts to help the player get accustomed to the game

It is so much easy to aim and press a button (or press and hold to make sure your aim is on point before releasing) rather than pretty much doing an Attack Move but for an ability.

It's really annoying how I have taught over 8 players this game and I have to go through the same process every time. "Skip the tutorial, it'll force you to adjust to things that will later on hinder your gameplay and mechanics" "Remember to unlock your screen, adjust your camera move speed if it feels too fast. Click Quickcast All then scroll down to the bottom and click Replace Quickcast with Quickcast with Indicator."

I don't even know why Quickcast with Indicator is even at the bottom of the Hotkeys page when I am sure it should be the third option at the top instead of the two.

It should say "Normal Cast", "Quickcast", "Hybrid Cast", or something like that.
