Advanced Tutorial Mode
Some information is just too important for new players to miss. To encourage them, if the player finishes it, he gets some IP rewards. Each lesson should be split into several quests to complete.
First lesson - Warding - 100 IP reward Using active items. Buying wards, upgrading trinket. Recommend spots for placing wards, such as dragon, tri-bush at top and bot. Learn to retreat when a ward spots danger.
Second lesson - Ping - 150 IP reward Using ping. Make a bot that follows the player's command in the process.
Third lesson - Timer - 200 IP reward Be aware of the dragon and baron timer by using Tab.
Forth lesson - Last hitting - 300 IP reward The players has to achieve 50% last hit success rate for 3 waves, 17 minions + 1 big minions.
Fifth lesson - Objectives A bot will try to destroy the towers farthest from you for 5 minutes. You have to reach there in 1 minute. It will try 3 times.
500IP reward after all lessons are finished.
I believe there can be more. These are REALLY REALLY basic knowledge, but they drastically help the players to go through hundred of games before realizing how important they are, especially warding.
