A small change to Tristana.
What do you guys think of changing Buster Shot from a point and click to a skill shot? Something like:
Tristana fires a explosive cannonball in the targeted direction. It causes 100/200/300 damage and creates an AoE explosion after impact with a champion, dealing another 100/200/300 damage and knocking away all affected units.
(Also, it would be nice to rebalance it around scaling from AD, because AP Tristana is a silly one trick pony. And her one trick happens to be "Annoy everyone with heal reducing burst and resets". :/ )
