I've been setting up my Paladin's Holy offspec for PvP, and I realized I need a lot of @mouseover macros to be able to heal properly. I know there are lots of folks out there who actively click their target's frame (or their actual nameplates! Amazing!), but I found out long ago I just don't work well like that. So, the first time I played a Pally healer seriously (way at the beginning of Cata), I created a ton of macros to ease up my healing and to allow me to keep a hostile target selected for interrupts and stuns. I was thinking of doing the same thing now, but my macros tab for that character is already pretty much full already due to things I need for his Protection mainspec.
Are there any good and simple add-ons that automate the mouseover process so I don't have to start deleting my Protection macros to make space for the even more vital Holy macros? Everybody tells me about Grid and other raid frame add-ons, but I haven't got them to do what I need them to do: they seem to rely on mouse clicks instead of keyboard strokes. I want is to be able to cast my heals and support abilities by pressing their keybindings while hovering the mouse over their unit frames, no clicking involved, while still being able to keep an enemy targeted. Are there any add-ons that do that?
