There are ways to do tutorials badly, and there are ways to do tutorials well. It does not stop the fact that they help new players understand the game. That is something new players need, because, right now, the current tutorial just tells them how to move.
League is a complex game, it will need complex tutorials. I would rather have several tutorial vids available to me rather than me feeding many games until I find out what works and what doesn't.
Also, as a side note, having good, indepth tutorials at least available without digging far would be nice. They would not be mandatory, but its something thats there for new players to reference while they play the game.
Last thing, you assume I ask this because i want to "continuously stomp noobs". Let me clear things up: I despise smurfs. They ruin the new player experience, something I despise even more. If they actually have a valid reason for smurfing (i.e. wanting to level with a low level players, wanting to see what would happen if they mained urgot from level 3, etc), then good on them. As long as those smurfs end their games like they would any other, swiftly and without BM. But for the type that wants to stomp noobs however, they thrive on the fact that the new player community is uneducated on the mechanics of League. They smurf for the sole reason of exploiting the unskilledness of players. If thats not a good reason for educating new people, I don't know what is.
