TL;DR: Notes about Healing. My ClickHealing implementation.
Based on 'Like a Pro' method. Healbot plus a semi-transparent-colored grid over it,
with two Click Bars (3x1 and 2x1) assigned to different toons/roles.
Dinamic. Type-of-action oriented. Not class oriented.

Every multiboxer has his own playstyle and I've seen a lot of different creative healing configurations. I use a hybrid method that uses some healing portions as part of the whole team rotation plus a ClickHeal zone where I can micro manage all the healing aspect of the thing, buff/debuff, CC and something else I might need.

I use ISBOXER and my configuration is (again) an hybrid model based on the 'Like a Pro' aproach merged with the multi step rotations model with a bunch of control toggles.

I got rid of all ingame configuration. Everything is set up inside ISBoxer. No macros, no skills on the bars, no bars. If I decide to create a new team or to build a new combo, I litterally just have to create the character set and it's done. Any class, any level, any combo. Press GO and play.

The ClickHeal zone was also built based on the 'Like a Pro' model explained here by Alge and than evolved to a more extense micro management center.

You need a unit frame addon. I used Grid for a long time but I found Grid maximum horizontal size too small to my needs. Now I use Healbot. The true is: this model don't need the addon to activate the skills, it don't have to heal or debuff or whatever. You just need it to monitoring purposes. It's shows the state and the conditions applied to your toons.

The Click Bars are designed over the units frame like Alge described on his post.

As an example of what can be done, I'll take my own setup:

a) I have 2 groups of bars side by side. Group 1 with 3 zones. Group 2 with only 2.

b) Each single zone is able to perform 6 different actions using LEFT MIDDLE AND RIGHT clicks with or without ALT. A total of 30 actions.

The 'Like a Pro' concept relies on virtualization so the actions performed by the bar clicks are dinamic, it means, if I LeftClick zone A, if my healer is a druid he'll cast Rejuve but if my healer is a priest he'll cast Renew or a Shield...

ONCE THE BAR IS SET, ITS ACTIONS WILL CHANGE BASED ON THE TOON YOU'VE LOADED (healer, counter, CCer, etc.)

NOTE: I don't think on skills or spells. I treat them as what they do: HOT, Flash, Great, Decurse, Buff, etc. This way, I can command my toons like this:

"Hey _<dude>_ put a HOT on the fkn tank, decurse, again, flash on him, flash on you, shield the stupid rogue, Damn! Soulstone on you!"

Every toon loaded will know what to do because it was previously set up on ISBoxer. When, for example, I RightClick zone C wich means 'CC the mofo', the lock will call the lady and seduce the mofo, but if the mage is the guy, the mofo will be sheeped, or hexed, or chained, or whatever...

c) Now, why 2 groups? I started with a 1x3 grid. But when I reached MOP dungeons it wasn't enough. Health pool raised lots, mob damage grown proportionally and healing became more intense and toke things to the limit almost everytime: mana problems, multi tasking, click things, while healing like a mad nurse with the 'me or him?' dilemma. So I needed something like an off-healer, let's call him an assistant, a paramedic, to get over control if healer was silenced or oom or died or went to the toilet.

Group 2 (1x2) bar commands a 2º group of toons.

So, Group 1 is mostly healing and cleansing territory. Group 2 is more Plan_B oriented.

As I said, this is just an example based on my own implementation. You'll have to find what fits your playstyle to give you a better multiboxing experience and more fun.

I think the most important thing about all I've wrote is the way how you think your actions when playing. The software routines and variables, key names, buttons, every technical aspect should vanish from your mind when you're playing. And the secret is a planned configuration based on VIRTUALIZATION.

A class/skill implementation will lead you soon to endless keybinding, action bars full of garbage and the inhabilty of reacting fast and efficiently when playing on a more challenging environment.

"Healer, POM and shield the tank!" - That's what you have to think.

ISBoxer will read it like this:

USER(you) alt+leftclicked the GROUP1, zoneA that performs the Mapped Key Action 'TeamHealing2' included in the VirtualHealing KeyMap. Nice! Now ISBOxer checks who's toon(s) have assigned that VirtualHealing is something. He found a guy! JohnThePriest! He has his virtualization set to 'hey looking for VirtualHealing stuff?' Check Level 90 - DiscPriest KeyMap. ISBOXER will look inside that KeyMap seeking the 'TeamHealing2' Mapped Key. Cmon, hurry up! It's there! The Mapped Key performs a Macro Action named 'Prayer of Mending' inside the Priest Set. Gogo! I got it: The macro is /cast [@mouseover] Prayer of Mending.

@Mouseover? Who is mouse hovering now? mmm, mouse is over the guy named SilviaTheWarrior. Ok, send it to WoW!

ingame: JohnThePriest casts Prayer of Mending on SilviaTheWarrior

Now what? The USER(you) rightclicked the GROUP1, zoneA ... GoGo ... ... ...

ingame: JohnThePriest casts Power Word: Shield on SilviaTheWarrior

ISBoxer let us use our own human instincts and skills naturally when playing, this is very rare on a software tool and means creative thinking and very solid knowledge. It reached an upper stage no other multiboxing tool has achieved yet - not even near. So lets dig it and 'get all da fat loot'...

Really??who fck care? Just "sheep the mofo!"
