I assume that somebody, somewhere, has done the detached corporate penny-pinching to make this all make sense on paper. But this is a disastrous move from a consumer goodwill standpoint. If you have the CEO of a studio which handed you a major commercial success publicly mourning the depth and scope of your layoffs, something's gone wrong.
Reminder for DnD fans that supporting indie publishing houses is an option.
Due to the OGL fiasco last winter there's now several non-Hasbro 5th Edition systems developed or in development that use either CC or the ORC license.
I'm personally waiting on Tales of the Valient (formerly project blackflag) and have copies of the Advanced 5th Edition books as well. But I'm sure there's more out there.
