Yeah I feel like the lists provided answer the question.

Fetter ward maxed is more useful than purify maxed IMHO. Fetterwar is one of th few skills I will avoid using when teaching new healers how to play their class in friendlies.

It's kind of a slap in the face to a rank 1 healer when I say, "You need to aqua fluid/Repose/Heavy me if you want to stay alive."

Then they hit me with all three, they still die because I can ignore proper opening moves. I will still use purify, because low ranks should have it also.
