No Sigils in Northrend? (Source)
I'm pretty sure there are some sigils you haven't seen yet.

Infected Wounds "misses" (Source)
Infected Wounds is a disease, so it can fail, which shows up as a miss in combat logs. Stacking hit should fix the problem if it seems to happen a lot. Poisons have the same issue.
Go-to spells for healing (Source)
In our minds, your go-to spells when healing anything bigger than a 5-player group are Rejuv, Regrowth and Lifebloom. You are probably not benefiting your raid the most if you are chaining Healing Touch on the tank while the paladin is trying to keep everyone up with Beacon of Light.
Healing Touch, Swiftmend and Wild Growth are all very useful spells. But they are intended to be used in smaller group or when something unusual happens in a raid. If the entire group takes a lot of damage at once, that's a good time for Wild Growth. If a melee dps class is very wounded and you don't have time for the bloom and Swiftmend is on cooldown, go for the Healing Touch.
Druid isn't the "fill in the gap" healer (Source)
If any class is the "fill in the gap" healer, it's the Holy priest. Their strength is in versatility -- they have single-target heals, group heals, instant heals and hots. The standard (but by no means only) way to heal a raid is to have a Holy paladin on the tank along with a Resto druid, have a Resto shammy AE heal the group, and then put the Holy priest wherever you need them. We are also trying to get the Disc priest into a role similar to the paladin, but based more around damage avoidance than efficient, quick heals.
