Dracul's is an acquired taste. It's one of the most pro items, and goes by a very high HR price on the soon to be late Ladder. When used in dueling, even more so, but there are so many other simpler mods that give a direct bonus without micromanagement. To balance out the lack of IAS on Dracul's, Smiters (especially Smiters) make up for it by using any combination or all of the following Auras: Defiance (defense), Fanatcism (IAS, damage), and Concentration (damage), as well as boasting the ever so awesome Holy Shield (damage and defense) ability.

As far as Trang Oul's Gloves go, they are definitely useful toward Rabies Druids, as well as Spellcasters who can't find/use Magefists. Depending on the item used, Strength to meet IK requirements is hardly ever a problem, unless you used a Phase Blade, where, in which case, your Dexterity must be 116 or higher, assuming you even have a Ravenfrost. I agree that it is implausible for most characters, but possible. Spellcasters, however, don't have the Vit to spare, and rely on Enigma.
