Be careful what you wish for...

I wish Gothmog's stomach would ache as badly as mine.

Your wish is granted. But pain makes him mad, and he's a better fighter when he's mad.

I wish Denethor hadn't killed himself.

Granted! But without his suicide someone else had to step up and kill his/herself. In the end the weight fell on Aragorn and the last heir to the throne of Gondor died.

I wish wargs had been used by Men and Elves.

Granted. The Wolfus Demonicus, or the Warg, primarily feasts upon halflings.

I wish the people of Middle-Earth realized that Sauron wasn't that bright.

They do some years before BIlbo goes to Rivendell. Everybody is happy, they keep saying, 'ah, this Sauron is not that bright, he'll never guess where the Ring is', 'ah, this Sauron is not that bright, he'll never learn where Shire is'...

Underestimation leads to the fact that Nazgul seize Frodo and force the Ring from him. I mean, he never moves anywhere, and is captured by the Bag-End smoking his after-breakfast pipe... sad story, but true...

I wish Blue Wizards would be present at the Council of Elrond and tell their story

Granted. They show up and tell their story. However, it is 400,000 pages long, means nothing and goes nowhere and ultimately they are cast into the river with heavy weights attached to their faces.

I wish Théoden had made Wormtong dress like a clown.

Granted. Unfortunately, Eowyn had a terrible fear of clowns and the moment she caught the slightest glimpse of Wormtongue, she ran herself off a cliff.

I wish Isildur had destroyed the Ring when he had the chance.

So be it. Isildur destroyed the Ring, because Tolkien got fed up with LotR and wanted to get rid of it quickly. That means that LotR was 24,7 pages long and no other books about ME ever came later. Sad, but true...

I wish Boromir was a gangsta rapper with tons of bling blings on his neck. (And a golden handgun.)
