What is the point of this? Are you testing GD?

HW was hard just because of Cleric Stance.

SB astro had time magic but there was also mana tick tracking. High level astro play required an insane two-minute burst rotation that is RNG (just look at any top log from that time). It also wasn't just about using Expanded Balance. The real ceiling is ensuring EB every 2 minutes while squeezing as much juice as possible between bursts, and that required you to tackle a complicated decision tree. Not even the top astros have reached the frontier back then, but we probably would see what that's like if AST never got changed. Before 4.3 you also had to deal with 2.5s slidecasting, memorizing a star script. And you actually had to use Aspected Benefic.

Scholar was hard in SB not because of the DoTs or Shadow Flare. Those were fairly minor. It was hard because of Miasma II and fairy micros. Miasma II locked you into melee range and only gave you a weave window every 12s. Manual embraces were required for top play, either to pop Divine Veil or to push healing from DPS to tank to maximize HoTs on the DPS, and this could actually save an entire GCD.

Does this sound fun to the ShB and EW babies? Somehow I doubt it. Which is why healers will never go back. It's a role for babies now.
