This is due to the fact that items found in TBC from Weiweismart's blog

If you're carrying all three, you can take the pants off. But, it's recommended that you keep these as a piece of transition to Burning Crusade Classic Gold use when you transition into the p3. It's not clear how non-humans deal with it. Maybe they don’t have to take them off all at all.

My resto shaman .... saw the screen change color, with a million tiny heals moving ..... This was my thing.

Edit: Trauma and the Glowing Twilight Scale .... because the healing of chain heal was considered a direct heal regardless of subsequent hops which could cause both these items to run like crazy and I could be healing 20 of 25 raid members at any given moment.

Edit: The four pieces of armor tier 10 which caused your target to get chain heal crits also got healed for an additional 25% in time. This was in addition to the incredible results you can be able to get as a Resto Shaman.

Chainheal isn't gear dependent. It's a game changer and it was a miracle! It can take you from "really excellent healer" to straight up "god the highest level"

The phase 1 gear is certainly more boring, in comparison to phase 1 Classic when you only had only a few choices, you've got a much larger available loot pools to choose from or sell for. Classic only had two healing weapons, and the KT hammer didn't drop. While we're only in Phase One, I have numerous healing weapons to choose from. Each phase also comes with weapons that are unique to each phase. While there aren't any super iconic items, like Benediction the upgrade of every one is a pleasant memory.

This is due to the fact that items found in TBC are more balanced and have various options available for each slot. The overall equipment in Vanilla is not much more popular than the gear in TBC. However, players will remember broken items such as HoJ gems, reju gemstones and edgemasters, which are stronger than other item that is slot-specific.

it's a bit more nuanced as "they did not know what they were doing at the time". they deliberately made poor items of high-level, as well as the low-level and end game bis objects that were "situational" (based on the situation as well as your gearing options and cheap WOW TBC Gold the strategy you were using) that allowed players to make "fun" and profitable choices.
