I cast Miasma II only when Contagionis off CD. Other than that I do indeed avoid it. Am I casting Ruin/RuinII, rarely. Rune II mainly for the Blind if I notice someone else isn't constantly spamming it making the DR kick in and making it useless. The thing I love about SMN is the ability to help out the healer a bit. Is it needed? Sometimes no, sometimes yes. But does making things a bit easier ever a bad thing?
