New nexus and inhibitor turrets are not strong enough

Each team has 11 turrets to defend however 5 of those turrets are vastly more important. If your team is on the loosing end of a game your inhibitor and nexus turrets were your last line of defense, they provided enough damage that it was possible to turn a game around if the other team is not careful. With these turrets receiving what some would call an adjustment but what I consider a nerf to turrets they no longer provide that defense. In the past when super minions attacked your base even though your towers delt constant damage they still could not hold the other team off without help. Now that the constant damage has been taken away and they are the same as all other turrets once you lose an inhibitor some one needs to be clearing minions at all time. Not only that but when the enemy team obtains the baron buff your team had the ability to wait it out if they played wisely, but, now the enemy team and minions are so much stronger than what should be the strongest line of defense that as soon as the other team gets baron they can push and end without even a hope of being able to contest the game. What I have found in the games I have played so far this pre season is that as soon as a team destroys and inhibitor turret they win the game and I find that it has taken a lot of fun out of the late game which should be the most intense and most enjoyable part.
