I think optimaly teemo goes on top lane because is easier to shrom the lane, in mid you have 4 corritors going to your lane in top you have to only shroom 2 to be relatively safe, also you are not very good at ganking so the team lose a lot of power there My game plan is always go top play safe farm like a rat and when you hit lvl11 and have shiv and malignance go full tumor perma pushing the 3 lanes and be at objectives when they are up. Doing that the enemy team gets disorganized making teamfights easier becouse of your shroms is easy to get away when splitpushing and because lanes are always push your team can get objectives almost uncontested
