I distinctly remember a time when Timewalking in sets that weren’t optimized to exploit the weaknesses of the scaling technology at the time (gems and enchants) was comparable to doing heroics in blues. Back when heroics weren’t completely brain-dead.
I don’t understand why we can’t have a middle ground between utterly and completely brain-dead heroics and super serious try hard mythics.
Time Walking that scales you to a static level and your items to a static ilevel seems like it should be the perfect avenue for such content.
