No, I don't remember the replayability the ICC patch had. Because it had almost zero outside of farming for hilt drops.
When you say "the days", do you mean the same days when an entire tier and its associated art was rehashed instead of a new raid and tier sets being made? The same days when the entire tier before ICC took place in two rooms (and one of those rooms AND an entire fight were rehashed for the dungeon) and where they couldn't even be bothered to give each class a tier set?
But no, let's pretend that Wrath was the high point of large amounts of high quality, replayable content. Let's also pretend the ICC dungeon set was "THREE new dungeons" while ignoring that Forge of Souls was some platforms and then a room with only two bosses, Halls was a long hallway with a wave encounter and then a gauntlet encounter; and all three of them were almost entirely made from repeated assets taken from ICC and Icecrown itself.
After all, it was such a """quality"" expansion.
