@Riot, your turrets do not even exist mid-lategame.
At level 1, turrets are definitely an obvious aspect to be feared. All players know of their 3-shotting potential at that stage. Even a
would question a level 1-3 dive.
However.
As the game continues to progress, that fear becomes exponentially less. To the point where even an adc can dive the double lasers of your nexus turrets and most likely come out alive.
Not only do they cease to exist damage-wise with a generous amount of armor midgame, but they give your enemies gold, AND help to deny cs. Some defensive structure if you ask me!
Above does not bother me even half as much as my next, and final point. Say you have a ranked game where you get fed early, and your team decides to just goof around a bit against a Jinx/Tristana. You get aced, and it's just their half-life tank which you chose not to focus, and a 10% life ADC with lifesteal. Within your 35 second death timer for your team: You have lost your inner turret, inhib turret, inhib, nexus turrets, and NEXUS!
With a game that revolves around buildings being a major focus, they are quite pitiful. One mistake, as shown above and also experienced in multiple LCS and Worlds tourneys, can lead to instant defeat. Even if you have 80% of your structures at 100% life.
TL;DR PLEASE MAKE BUILDINGS BE HELPFUL
