Can you access old dungeons as regular level when they're on timewalking M+ rotation?

Is it possible to access old dungeons as their correct level/difficulty range when they’re on the timewalking rotation? For example, Grim Batol right now.

I’m asking because I was just wanting to work on some old achievements.

Yes. You can set the difficulty before going in

So setting it to normal will take the M+ version out

I believe you can, only on normal difficulty though. And only if they have normal difficulty.

Yea, I should have clarified that I need it on heroic mode for the achievement(s) I’m wanting to work on.

I guess I’ll just queue heroic and convince group to do it or else wait until the end of the season. (Sidebar: I don’t do mythic dungeons …hate them with a passion. But, I feel badly for you all having to do the same ones over and over until the end of February …when there are so many more out there they could rotate through every week or two.)

Ah, gotcha. Unfortunately you cannot do them at their release level during the season. We can’t really know if they will add this moving forwards, it would be neat if there was a way to shift it to the low-level somehow though.

Either way, I wish you luck dungeoning, hope you can get it done before next season!
