Ah thanks for the info, I think I got a few missions into NF before I stopped playing. Is there a reason to use a N/Rt for resto instead of just using another Rt or is it just the number of RT's you end up with?
I think people have mostly abandoned that N/RT--it used to be part of the "Sabway" 3 Nec build, where you simply use those 3 Nec heroes and any henchies you want. It was quite unstoppable for most of Hard Mode. This was before they allowed you to fill up your team with heroes.
The balance for that is soul reaping--You know, how Necs get energy regen after something dies. Even after the nerf (now it occurs only 3 seconds, or so--not giving you the energy bomb when wiping out a mob at once), it is still effective. Adding a MM to the team that is effective at blowing up its own minions, provides a constant stream of energy to your healer Nec, so they tend to be much better healers than monks. I always added in a Prot monk as backup (always preferred prot to healing, anyway: preventing damage > healing damage), but prot is generally out of favor, now. Whatever, still works.
Now that you can add all heroes, the two Rits--using Razah as a Rit, though he can be anything you want him to be, is another constant energy prot/healing build. You get the advantage of spirit shields. While minions are great as meat shields, they are somewhat unpredictable. spirits act as nice walls that keep your back line out of danger. Spirits are also now instant-cast--most of them, anyway. I remember most of those rituals taking 2-4 second cast time, so this change has made them much more useful.
MM isn't as favored, anymore, as you run into places that don't provide exploitable corpses (though I think the change to Aura of the Lich allows for exploiting previously-unexploitable creatures, like elementals and such, though I'm probably wrong about that.) You also have the problem of Minions running off and aggro everything.
