Aye!
The game effectively had 3 different types of healer:
The rune priest/zealot was the games traditional healer, regular heals and fairly straight forward buffs.
The Archmage/shaman was the alternative caster styled healer, their gameplay revolved around balancing healing and dps to charge a secondary resource for additional abilities. Think FFXIV's Red Mage but instead of white/dark nukes, you're juggling heals and dps to charge that bar and get the prize at the end.
Lastly and perhaps most distinctly, the Warrior Priest/Disciple. This was a melee class with very very basic raw healing spells, instead of being MP limited, your melee abilities generated charges for your proper heals with an emphasis on party wide abilities to allow you to focus on your meleeing. Whilst it wasn't perfect, I still think that this job was one of the best and most original healer concepts in any MMO to this date. It's a huge huge shame that SE didn't base RDM on it IMHO!
It's worth noting that whilst the healer jobs were tremendously enjoyable, many people would question the balance between them which is pretty fair. The more diverse the jobs, the harder it is to keep them balanced across a broad spread of content.
