Fun meta.

Janna mid. Rush banner, take dematerializer and teleport, max Q. Sit in lane and throw tornados at the wave for 15 minutes until you finish banner, then throw tornados and super tanks at the wave for another 15 minutes. Watch enemy team futilly roam and scramble as you take towers in seconds. Auto the wave while throwing tornados and tanks and walk back the second the enemy does anything remotely threatening, and still win the lane anyway.

Works best when you get the other laners to build one too and send 3 baron buffed supertanks and luden's charged tornados at said minion wave.

Fun times. Really.
