Melee 5 boxing?

So I have heard of people multiboxing 5 ret pallys or 5 rogues, and I have to admit I'm clueless as to how.

I have 5 druids now at lvl 45. I'm using an i7 machine with keyclone and jamba, and I'm using a focus-based leaderless system.
I've been balance up untill now, but I figured I'd see how feral would be just for kicks.

My problem is this. I run up with my lead toon in bear and start pounding the mob. My other toons follow in (in cat form), but stand a few feet in back of the leader and don't hit anything. So I back up a bit on the leader and bring the mob back through the followers so they turn around and start hitting the mobs back. It works fine for one mob, but it gets hairy for group pulls. Even worse, when there are runners...my leader toon is following behind and hitting it...and all my other toons are way behind doing nothing but running.
It seems to be way slower than leveling boomkin, and I can't imagine how this would work well in PvP yet I've been told people do it.

Now I've never played melee DPS or a tank before I started 5 boxing (holy/shadow priest) wo am I missing something big here?

Any suggestions?

To make the most out of a melee team, you need to enable click to move on your slaves and set up a key for interact with target. Using follow strobing in Jamba is also very helpful.

Select your target, tell your slaves to assist you, hit the interact with target key. They will run up to the target and attack.

Even with the interact with target (which your going to want just for the ease of interacting with NPCs and perhaps looting mobs) your going to want that 'wiggle' to be something you have mastered. So you likely turn the mob a bit with the tank and let the melee dps get a flank on the mob, this you will end up doing most of the time it seems (and praying your guys dont randomly decide to interact with unaggroed mobs ... dont spam interact with target if not needed)

The trick with melee I think is to be able to rapidly perform turn overs from one mob to another. Where in a tank+caster situation the turn over is easy since during the casting of spells you would be able to switch targets and not have idle time.

I found it useful to do this on the PTR or as deathknights a bit to get a feel for it, because low level characters just don't work the same higher level characters (a whole lot of missing and being dodged). Then go back to the low level characters, just like low level casters. I found it was just easier to do mundane sequences (heroic/sinister) versus trying to play like a solo player and actually do the finishing move.

I also found overkill or resource waste to be a problem, I don't know how to resolve it really. It happens with casters as well, but melee characters seem to have a lot more fight expenditures to manage (combo points, rune sets, rage). So where a caster might have a mob that is going to die from one caster's spell, you still toss 4 at it.

For your warrior + rogue group, you likely want to have the combo points visible in some fashion just like a dk would or have parrot setup to spam under a unit frame that your at 4 combo points or whatever.

Thanks for the responses.
The part I was missing was click to move. I thought that was like the Diablo 2 interface and would require mouse broadcasting. I tried it and my melee DPS still could use some work, but at least now I'm hitting things.
I appreciate the info.
