This pretty much sums it up.
On top of it all, there is no real reason for downtime between healing phases to be as high as it is. At least in savage and ultimate modes, forcing healers to spam their GCD heals should be nothing to be afraid of.
If developers are ok with having me spam Malefic over and over, they should also be ok with having me spam Benefic II non-stop. On paper I'm still just spaming one button, but at least that button does what my job is supposed to do.
