Priest. Another class = more fun. In addition, as I noted before, priest gives you two new possible healers: a disc priest or a holy priest whereas all other healing classes only have one option.

This may be OBE at this point, but here's the best balance druid macro I came up with (one button spam):

/assist focus
/stopmacro [channeling]
/castsequence Moonfire,Sunfire,Wrath,Wrath,Wrath,Wrath,Wrath,Wra th,Moonfire,Sunfire,Wrath,Wrath,Wrath,Starfire,Sta rfire,Moonfire,Sunfire,Starfire,Starfire,Starfire, Starfire,Starfire
/castsequence reset=0.3 0,0,Starsurge
/castsequence reset=0.3 0,Starfall
/cast Incarnation
/cast Nature's Vigil
