After all, first thing they tell you is that tropes are tools of the trade.
And that is TVTropes biggest flaw.
At its heart TVTropes is a literary critique site. I would argue it's a very bad one, that ignores vast amounts of the historical literary critique surrounding it, but it's still a critique site. You cannot use trope like legos and create something. Rather when you rip the heart and soul and everything good out of your work, tropes are what is left. What you can use tropes for is looking at your work after and seeing if anything you don't want has crept into your work without you realizing it. And even then only so much. It's easy to be blind to your own faults.
Now what do you do if you do see a trope you don't like in your work? Well if its something simple, like "Crap, I described the evil nation as being darker skinned then the good nation. That's got shitty implications," then you can simply cut it out or revise it. But if your problem is "my MC is a Mary Sue," then you may need to look at your work as a whole. Because it's likely the core of your story is "look at how awesome my OC is," and that kinda story only flies with your buds at RPG night. Those kind of issues require fundamental alterations to the core story, not looking at the trope checklist and trying to "subvert" things.
