Riot we talk about how weak towers are?

Ima use this game as an example. For those of you who did not see it, let me give you the summary. TSM was dominating, until, at 35 min they get aced from a bad baron fight. Their first and only real mistake in the whole game. Enemy team (4 people) proceeds to, in a single push, destroy all 3 of their midlane turrets (even the first one was up) + Inhib + Inhib turrets, and nexus to end the game.

While i do belive a mistake at this point of this game should be punished, There shouldent be ANY scenario where a single ace at 30 minutes allows a team to push in 5 turrets in one go and end the game. Thats absurd. Even the COMMENTATORS where baffled, saying that "their is no way they can push everything in"

Turrets need to be buffed or something needs to seriously be nerfed because this is just ridiculous.
