It's fair to be skeptical of Mitch's abilities as a writer given that this is his first official rodeo as a games writer.
It's not all that different as putting your trust in a new joiner to any company to lead a project on his own. He's not proven himself, he's green, etc.
That being said, even if the relative skill set needed to be a writer/reviewer are similar, the jobs are very, very different.
He may not have been a stand-out reviewer in the same vein of Simon Parkin throughout his career, but who knows if his true talent will shine as a video games writer.
Ultimately, he is hired to be a writer at a major publisher-owned studio, a company that should have no issues receiving applications from the most experienced/talented writers in the industry. I know a majority of games-writing are hot garbage, but he is hired/chosen by Jade Raymond over presumably dozens of other interested applicants.
Let's see what he has in-store.
