Do healers have to be easy to play?

[Ilyrian]

The same can be for all roles easy intermediate and difficult. This would do more for player interest. Also it doesn’t mean one or another is more powerful it just means the skill level to play effectively is higher.

Preventative healing (i.e shields) is arguably easier than reactive healing. Blanketing a raid with shields to mitigate a player's mistakes before they happen is easier than reacting to player error whilst the healer is also having to navigate the same mechanics.
