Ranger/Monk Question

Will I be able to heal my pets? also since I plan on standing back and shooting while my pet tanks. is Monk/Ranger a better choice?

Also are War/Monks better PvE Soloers and farmers?

Yuppers, you can use COMFORT ANIMAL to heal your pet. This skill also doubles as a res for your pet.

I've read that the best soloers/farmers are R/Ms.

yes you can heal your pet with your beast mastery skills and also with your monk skills like orison of healing, and so far the consensus seems to be RA/MO to be the best solo farmer

I find that just using comfort animal is enough to keep your animal alive!
