To be fair, this analysis is still made in a vacuum and if you read the whole thread, the author later states that taking raid buffs into account, it will be either a buff or nerf depending on your party composition. However any panic regarding some massive dps nerf is indeed unwarranted.
That said, most people remain salty about what is illustrated so perfectly in the earlier mentioned picture rather than any presumed dps loss.

This would be a stronger argument, if not for the fact that we've already got a tank job with very similar playstyle.
