Idea to change towers a bit (or a lot.)

Alright, so we know that towers are a threat in about the first 5 min of the game but after that, any tank could just sit under them and not worry. I would like to see a change to that (mostly because I've been on both sides of the coin and realized I didn't like this current concept.)

Problem: Towers deal no damage to tanks.

Solution: Have the towers deal max percent health true damage to champions. This way it wouldn't matter who you were, everyone would die just as fast as everyone else. Now I'm not saying like 50% damage to where you die in two hits but more like 20% so that it would pose a threat but also still leave it open enough for those who can jump in, kill, and jump out.

This solution could bring up another problem though and that is teams taking towers without minions. Now I think doing that is stupid to begin with but beside the point. An added solution for this problem though is to create an item that turns tower's true damage into physical/magic damage to the champion with the item. This would allow for teams or team members specifically to decide if they want to have a team comp that can dive towers or not.

I would enjoy feed back on this idea. I will also love any rioter who could either look at this and try and do this or explain why this is a bad idea.

Thank you :)
