Mythic 20+ is about constant massive output, clever pulls, using numerous defensives and offensives with synergy, numerous mechanics at the same time etc.
TBC heroics were just completely different. There were SO FEW defensive abilities that it was almost unrecognisable. That's the main thing that people forget. On top of that, 360 degree one-shotting cleaves were not particularly rare. If you stood it in as, say, a Rogue (and it wasn't telegraphed in any way), you were instantly dead.
I mained a Rogue in early TBC, which is why I use them as an example. You had to actually spec into Improved Sap in Sub, something you'd otherwise never get. Otherwise you'd literally have to Sap, then Vanish, or you'd instantly die, as your untalented Sap simply had too short a range to be able to be safely used without half the mobs instantly one-shotting you.
On top of that, some of the mobs were just HILARIOUSLY overtuned. Anyone who did Old Hillsbrad on release knows what I'm talking about. Regular guards on the first trash packs would 2-shot a fully Kara-geared Druid tank. It was really retarded.
Cata? They weren't particularly difficult. Many dungeons were much easier with dedicated CC though. I was a Warlock and early on we ran with an Spriest too, and that was more than enough CC. MC was super strong on some of the pulls, and talented Warlock Fear was enough to survive any pack in any dungeon, even in early blues.
On top of that, it was super easy to gear up in Cata. Gearing up in TBC was a very, very, very long, slow process, second only to Vanilla in that regard.
