Why must turrets be such a flawed gameplay element?

What they do: drag games out unnecessarily, provide false-hope "safe zones" (a.k.a. gravesites where you are a sitting duck), only kill minions, let an enemy snowballing team snowball further.

What they don't do: ever make meaningful contributions to countering a gank/dive/dunk, provide any element of fun, work in your favor.

What they seem to do: assist the enemy team's ganks by letting them pin you down in areas of "false safety", steal your CS, make gameplay stagnant.

What should happen to them: REWORK.

Seriously, turrets aren't a good thing for the game anymore. A big statue that shoots at people? What the crap? What's the point in those?

(By the way, I'm TRYING to sound cynical.)
