New Towers Prevent Comebacks and Promote Stomping Only

... Except not. I played a game yesterday as Talon (assassins are dead qq), and we were 46-80 in the enemy's favor. They had a Garen, a Kindred, and a Corki (maybe he isn't Graves but his AOE damage is crazy when playing a melee assassin). This, coupled with Zyra and Braum's CC meant we were getting absolutely stomped. However, what did we do? We turtled (but that's impossible now qq). Our Fiddlesticks stole a Baron but the fully built enemy team attacked our base anyway. I decided to go on the offensive, and took the mid inhibitor. Corki and Kindred backed so I used Baron minions to take the top inhibitor turret and then one shot them (assassins are dead qq). After this, I took the top inhibitor and one and a half nexus turrets. The rest of the team recalled at this point so I evaded, but Vayne teleported in and took out most of the nexus. I e'd onto Garen (closest to Nexus), ulted into invisibility, got to the opposite side of the nexus and took it out.

None of this would have been possible if I did no damage to turrets.

tl;dr Weaker turrets make comebacks easier, as you don't have to be ahead to take out turrets while the enemy team is thinking they are stomping.

Although the preseason sets an entirely different pace and forces us to respect ADC's as strong duelists (why does Corki out-damage a similarly built Talon mid game, Riot? Aren't assassins supposed to do more burst than ADCs?), if you accept it and take advantage of it, you can win ANY game. I have lost 2 games as Talon so far this season, out of at least 15 games.
