Game Of Thrones: 10 Worst Changes From The Books

10. Killing Off Stannis

Stannis really didn't have a lot going for him. He was hot-headed, stubborn, and lacked a sense of humour; combined with having a penchant for religious fanaticism, it was a recipe for disaster. The last we saw of him, he was surrounded by dead men after Ramsay wiped the floor with his army.

When Stannis was defeated by Ramsay, ending his bid for the Iron Throne, it solidified Ramsay as one of the key antagonists in the show. This completely changed the trajectory of Martin's story. For one, Jon was forced to spend an entire season trying to rally enough men to defeat him.

In the books, Stannis is still camped in the woods, not far from Winterfell. His army is in pretty bad shape, but they've laid a cunning trap to lure in the Boltons. Everything indicates that Stannis will likely defeat the Boltons, (or at the very least Ramsay), meaning the Battle of the Bastards won't take place.

Although that scene made for some great TV, it resulted in huge amounts of screen time being taken away from the Walkers - characters we never got any solid answers about.

Jon will likely warg into Ghost before being resurrecting, and gain some insight about the Walker threat. There's even some theories that believe the White Walkers will use Jon's body for some dark sorcery.
