I always refer to healing as using two different possible playstyles: active and passive.

Passive - you setup a passive rotation that keeps your group topped off. Sometimes you may deviate from that and intervene from that process, but for the most part, your healer is going through a set rotation. I would consider Ellay's setup above as passive, even though he is occasionally changing focus and having to make active decisions whenever it needs to happen. In reality, it's probably more of a hybrid, but from a setup, configuration, and playstyle perspective, I consider it passive, since there's less spell selection, and a rotation is being followed. Shamans and Monks are probably best played with this setup.

Active - Your healer only heals whenever you tell it to; you determine each spell cast and when its done. This is more akin to clique style healing although you definitely could use keybinds and focus targeting. It plays well for some classes (Paladin), and terribly for others (Druid).

I, myself, prefer an active healing style. I have clickbars and my spells are macro'd in ISBOXER using mouseover casts. It feels more natural to me and it feels more like I'm actually controlling the healer rather than intelligently designing my way around playing a healer. That being said, as someone who has pulled a resto druid into +5s, it's nearly unplayable to heal as a druid in that way when a lot of damage is going out, unless you have some seriously amazing multitasking skills. Unfortunately as a resto druid if you get behind it's incredibly hard to catch up without burning cooldowns, and you almost need to have hots rolling 24/7.

In talking to other multiboxers playing at a mythic+ level, for druids, they use a set passive rotation. They roll hots across the team, Wild Growth and Efflo in the rotation as well, keep lifebloom on the tank, etc. I've seen some guys have a 12 step function in isboxer where it quite literally does all of these in one motion with one key. Not for me, but if I'm being realistic, it's probably the best way to use a resto druid and I probably wouldn't play one without it.
