Tower need higher armor penetration / straight up deal true damage

that the tower are way too weak is a common thing people complain about ( Loosing an entire tower after 1 gank even if the tower full HP ) but what mocks me the most is that tanks can pretty much tank it forever without even caring that the tower is even there. In my opinion the tower should really scale better in terms of damage into the game, at early levels the tower damage is fine but after 10-15 mins the tower just become objectives that you need to protect but that offer nearly nothing on their own. there are now mostly 1-3 tanks or people that stack armor in general per team who can tank a tower literally forever so it's becomes nearly completely useless
