Tank+ duo help

[d07.RiV]

Hi,
I've leveled several character pairs on x3, and I'd say that pally tank + druid healer is by far the easiest combo.
Since other players tend to take damage, it might be difficult to macro the healer to heal them because /assist macros suffer from latency - for this reason pally is great because of WoG/selfless healer which instantly heal for full hp in 1 click (up to 80 at least, I didn't dualbox beyond that).
Druids are extremely easy to use because all you need is to put a pack of hots on yourself and you're good to go. Plus there's the treeform CD if you decide to pull the whole room. In WotLK instances healing is so overpowered that I can easily pull like half the instance and never dip in hp with just 3x lifebloom + rejuv.

I also like a couple that assist the main toon.

That doesn't work for me, because it takes a second or two for your other window to recognize you changed targets on your primary character, which is absolutely no-go when you need to urgently heal someone up.
