Bungie explicitly said they aren't going to do this. MMO-ish gameplay like Destiny naturally regulates this type of debacle.

The old toons get to start from where the previous expansion left off, and play through the content as soon as the new expansion launches. And it's not "writers at Forbes."

He doesn't know what he's talking about, and he's not even they're regular Destiny writer. Thankfully, Bungie doesn't spend millions of dollars developing games based on his opinion.
