Make the towers prioritize who you're attacking if nobody else is there. (Excluding minions)

If someone is running at me through my towers and minions are there and I turn to attack them so they can't catch up, make the tower target them, or if they're diving me then let that be an added risk, it will add strength to towers and make them more useful, a good way to make them better.

Another good example could be if someone is pushing in your tower and they over extend and you catch them under it, it should target them, not wait for them to attack you, they're in its range so they deserve it, now I don't propose people get targeted just for being in tower range, it would only be if they stayed for too long for you to attack them, will make people have to think a bit more.

What do you think guys? Might be a good way to make them stronger... Thanks for reading :)

Edit: Would also help with those times that they're just attacking the tower for free and ignoring you...
