Another extremely popular setup is some combination of a solid raid frame, like Grid, and a more configurable click-to-cast mod, such as Clique. Healers can then establish that certain mouse buttons cast certain spells whenever the mouse is over the player of their choosing. As with Healbot, this kind of setup works best when you remember which spell you put on which button. It feels a bit more sophisticated than Healbot, and chances are you'll want some other raid frames anyway, so it does feel relatively natural to shift in this direction.
Meanwhile, at the bottom of your screen ...
All the while, sitting down there unassumingly are your action bars. These gives you the visual clues that most mods lack as to what is on cooldown and which key corresponds to which button. This bar works after patch day and every day, right out of the box. You can place spells on a bar directly, or you can step things up a bit and employ various macros by placing these directly on a bar. Reassigning a spell or macro is as easy as drag and drop.
The only drawback with this approach is that it will often turn you into a "clicker," and the lag introduced from first clicking on your desired target and then finding and clicking on the appropriate button can definitely add up. This is particularly inconvenient when the game has opted to place fire under your own feet as well as those you need to reach out and save. You begin to feel a bit as if you're playing a pipe organ, and your attention gets split between a very busy screen and the job you've volunteered to do.
A different type of mouse
The fine folks at Razer have developed a product that solves a bit of this issue in a couple of different ways. The Razer Naga is a typical five-button mouse with a not-so-typical, cell-phone-style keypad underneath your right thumb. Razer provides a mod along with the mouse that can reshape your action bar to match the layout of these keys, giving you a visual reminder as to which button has which spell or macro. Their mod can also automatically rebind each and every action bar to a mod-key, such as Shift, Ctrl or Alt, and number combination. You can reshape those action bars as well, and you can position them anywhere on the screen that you wish. Again, you have a solid visual guide as to what exactly Shift 7 will do, for example.
Combining this device with the action bar setup alluded to above can cut your lag considerably and will likely bring more of your spells and macros within reach. You're still in a bit of an unnatural position, however, clicking on the player with your mouse button and pressing the desired spell on the keypad.
Putting it all together
The step that bridges this gap has actually been around for a very long time: the mouseover macro. A mouseover macro will look a little something like this:
/cast [target=mouseover,help] Lifebloom; [help] Lifebloom; Lifebloom
This macro looks like Lifebloom, and it reads that way when you mouse over it. If pressed while targeting someone or without a target at all, it will cast exactly as if you pressed the spell button. If pressed while your mouse pointer is over either a player or an eligible unit frame, however, it will cast the spell on that target instead. After some swift copy-pasting and a little diligence, you can configure each of your targetable spells in this way.
Going back to our Naga setup from earlier, you can now simply hover your mouse over the target in need and press one of the 12 buttons under your thumb. We have now achieved point-and-cast with all the spells and macros your action bars will hold -- without sacrificing visibility.
With a configuration such as this, a healer doesn't need two or three go-to spells; he can use them all, and at a moment's notice. The wide array of abilities that we healers have can finally be fully employed to allow us to raise above being simple fillers of green bars and become invaluable assets to those we support.
It really is a beautiful thing.
