Depends on what sort of playstyle you are looking for.
Most RvR groups will expect you to run high Nurture and play a support heal+peel role. Getting at least red body resist and PBT is advisable.
45 Nurture 33 Regrowth 10 Blade
Then spread the rest of your points as you please. Be reasonable though, going 47 Nurt for the higher DMG add and Haste will probably yield more DPS than a couple more points into weapon for example and at that point you might aswell go for red resists.
For a group-spec, I would advice just going full support
49 Nurt (full suite of red buffs) 42 Reg (bigger, faster and slightly more mana efficient heal) 10 Blades (side snare for peeling) Rest Parry
If your prefered playstyle is solo or smallman, that obviously changes.
