Judging from the upcoming patchnotes they nerf hc's. Also, if they were to make hc's harder with next tier of gear, they will more or less cut off the casuals and the alts who dinged a fresh 85 from doing hc's. The thing I more or less hope for but don't expect is that they just add a difficulty level. Keep the normal and hc mode the way they are now, but with next tier of gear, just add a super hc mode (or whatever the name can be), where the current raid gear drops (i.e. 359 gear).
