Hi guys.

I need some help deciding on a class combo.

Some information first. I dual boxed back in Cata with a priest/warlock pretty much purely doing quests so I have experience with dual-boxing.

Me and a friend have decided to get back into wow (again!). We really enjoy 2 manning our way through instances as pretty much the only way to level. Last time we returned we played a druid/priest and the time before we played a warrior/paladin combo. Both combos worked really well up until around level 68ish. After that it became really hard to 2 man dungeons for us.

This time I've decided to get passed that barrier I will dual box 2 characters, while he'll play 1.

He's probably going to play either a warrior or pally tank, so I'll need to figure out a duo combo that can heal.

So my question is,

What is the best duo in this case? preferably at least 1 class that can tank and heal
