Quality of Life Feature - Auto Skill Levelling
What if, just like Item sets, you could set a skill level order that would automatically unlock and level skills on level-up? This feature would be on by default and set to the order recommended by Riot for each champion, including odd skill orders like not putting additional points into Tryndamere’s ultimate.
You could toggle auto-level for the current game in the in-game options or turn it off permanently in the client, where you could also create your own custom skill orders.
This feature would remove a little hassle from veteran players, help new players, and also enable super clean level-spike plays.
