User blog comment:Emptylord/Blogs/What if summoner spells had to be chosen in-game?/@comment-6906412-20130825192730

Just reading the title of the post, I thought you intended something like SMITE's (the game, look it up if you don't know what it is) spell system where you can purchase non-refundable and unsellable spells (max. 2) that function like the summoner spells in league, each of which has three ranks with the last rank having an additional effect. SMITE gives players the option to buy a better item or a weaker item and a spell or two at the start of the game rather than your idea of using skill points to have summoner spells. Look up the SMITE item system for more ideas on this.

In theory you have a decent idea here, but in practice it would probably mess up a lot of different playstyles/champs/lane matchups (make them overpowered).
