Tutorial Game Mode
League needs a better tutorial mode for teaching new players.
My idea is to make a game mode that you can queue in called tutorial, have it able to be queued against bots or against other players. In this mode minions that are within last hit range are highlighted so that new players can get used to last hitting, all enemy champions have their auto attack range indicated around them similar to how the towers are, and enemy ultimate CDs and summoner spell CDs are shown as well.
Also tier 1 and 2 runes should be removed from the game, only tier 3 runes should be available and they should be way cheaper than they are now and a full set of a basic rune set should be pre-unlocked for use as they level up. Four mastery pages should get auto built as well, one for tank, one for ad, one for ap and one for support.
