The ENNH route is only good if you planned on getting it long before now (or if you will get it later) purely because the 100 Blood Gems of the Archfiend could take more than a full week of full botting (about 15-20 per day probably) and the rest of the Nulgath Reagents required are all at the max of their stackability, possibly taking another week or more. Probably will take nearly a month or 3 weeks to get the ENNH.
Put that on top of the 2 Roentgeniums of Nulgath, the 10 additonal Blood Gems, 30 more totems, a Warlord of Nulgath which just adds to the pile of reagents, and the other stuff which can take more than a couple days then you start to fell like it is better to just go normal.
