Towers should be more interesting.
Riot has done a decent job with the jungle. They made new objectives, gave us awesome season 6, took away the awesomeness of season six, and gave us ....plants. They clearly demonstrated creativity that made game play more interesting. I don't see why we can't have that same creativity when it comes to towers. They are pretty much the same. They do no damage and really don't interact well in the players in the game.
