cleric/ranger or sham/ranger

[Extunarian]

I don't think a ranger/cleric would be very viable, though it could be a decent base for a group. If you're going to go melee+cleric though you should pick a real tank.

As for shaman/ranger: When I started on this server and didn't know anyone I used to duo with a ranger I met in Blackburrow. We basically did all of levels 14-29 together and they went really fast.

I think the basic strategy was ranger pulled with an arrow and I grabbed agro with Insidious Malady (disease debuff), slow, and disease and poison dots. Once I had landed those spells the ranger could never take agro back. Then they would snare and I would kite the mob around with the ranger meleeing/shooting arrows.

Track+snare+extra melee DPS is a wonderful addition to a shaman's repertoire, especially in big zones like the karanas.
