I think SE should make it a bit easier for us to /war.

Depends if the mob can potentially one shot you or has en added effects, which while it's still missing most of the time, are still very highly annoying (enstun/enamnesia/enpetrify: annoying, endoom: screw you). /War should be safe for many Nms in Scars/Visions/anything not described above in Heroes however.

Very true. Tanking Shaula or Alfard comes to mind Death Scissors can easily one shot you unless you gear for PDT or get HP Atmas. Serpentine Tail may be easier to survive, but it will toss you all over the place and make him a pain to tank.

I'd still go with /NIN at Lv90 purely for damage, even if I rarely cast shadows at all (unless it's one of those annoying mobs).
