I know what you mean. I just spent awhile on my Necro/Swordsman slaughtering Liches and Lich Lords in Ilsh for their Necro Regs, 50-80 total of various necro regs isn't bad. Sure beats the hell out of recalling around on my mage with a giant beetle in tow buying up the small stocks of Necro Regs at various Mage Shops and waiting for them to respawn. Too bad they shoved all sorts of other crap in with the Ancient Liches in the Ethereal Fortress, otherwise i'd be farming them for 150-200 total necro regs per.
With Overseer Sundered Blade and the new Conjurer's Trinket talisman, my Necro/Swordsman rips right through Liches, especially after Corpse Skinning them. Can easily stand toe to toe with LL Paragons and kick their ass, gotta love the Leeching of Vamp Form+Curse Weapon.
