Teachers for new players

Similar to other games, I would like to suggest that once a player reaches perhaps silver 3 or higher (ranks can be changed) and has a good amount of friendly, honorable, teamwork, etc. They should be offered the option to become a "Teacher" A teacher is someone who can help out lower level players by teaching about warding, itemizing, strategies, what things may be called such as river, gank, etc. Low level players may request a teacher/guide and perhaps a vs AI or special type map and/or game mode with other teachers. This way teachers on other teams can communicate and help cooperate with everyone. Now obviously this is vulnerable toxic people to tamper so a base limit must be set in rank and commends for the person to be offered to be a teacher. The player who requests help at the end will rate their guide in a few things like quality, friendliness, and overall helpfulness. To make people want to be teachers special skins could be made specifically for that to prove a person is friendly and hard working in their community, or coupons for a level skin/champ in price value, or with the new Hextech crafting coming out something through that. Personally I would love to help new players out. Too many times friends of mine have quit because they either picked a champ that was difficult for someone new to get, didn't even know what masteries are and are repeatedly beat in games. This idea is very basic and is open to any suggestions or criticism. Just imagine, a good player playing with a level 5 summoner teaching them everything from support/adc to how a quicksilversash removes the ult from Zed. When, where, and why everything is done can make things way more interesting and I hope you guys give this some serious thought. Other games have implemented this many times with success now. A player who knows what they are doing are much more likely to not be treated bad by toxic players than someone who doesn't. It could change their choice about the game and weather or not to stay.
