U want fun on ashe? Don't recall till you hit lvl 6, soon as you hit 6 recall. Send arrow down mid with a ping, mid gets free kill. Team proceeds 2 worship you, other team mids proceeds 2 qq. Gotta love the milkstache.
Definitely fun. I have also done this one: Ult from base when a low enemy is hitting your tower when there are about 2 creeps left. By the time the arrow gets there, they are just backing up as the last creep dies, but they are stunned and the tower finishes them off.
