Some good info in here and some good discussion. In most of the previous MMOs I've healed in (I usually tank, but enjoy healing on alts for a change of pace), I've generally used add-ons or macros to mouseover heal, as I find it quicker and easier for my playstyle. I really appreciate everyone bringing up the pros and cons in regards to FFXIV so I have a better idea of what to expect.

So basically, thanks!
