Not exactly. You don't want to spam necrotic since you just refresh the debuff and use a death rune to achieve little. You're not usually going to kill someone with NS. That said, you still want to use BT to free up a rune for NS when it is necessary. I usually HB on plate and FS while using BT to bring back death runes to NS, and switch to OB for cloth or when either target is low. That's when I'll pop PoF and burst with everything I have.
i test necrotic and obliterate on dummy lvl 90 with my 2h ilvl489 .necrotic avg hit 29k and obliterate avg hit 75k.
in pvp everyone have around 60%res-25% pvp power =35% obliterate hit 48k on cloth no crit and necrotic hit 19k+26k healing absorb
so we should use obliterate with km on cloth and leather i think
