Best class to duo with a ranger?

[Lagaidh]

If you want a challenge, pair up with a paladin.

I've said many times on this forum, in Live, my dwarf paladin, and a half elf ranger named Toraque pulled off all sorts of crazy things.

It was the greatest complement we ever got one day when a DL group mate told us we squeezed everything out of our toons.

It's not easy, and the min-maxers would frown on the efficiency, but damn it was fun.

Here on p99 I pair my pally with my wife's druid. It's sorta ranger-y.
