I mean technically more difficult to kill, yes, but you put Ahtieli against Istendil and I put all my money on Istendil. Same goes with Zorszaul and even Satebos. Liches now are ridiculously difficult to kill because it's damn near impossible to properly command deny someone through more then 15-20 rounds of combat. Eventually RNG works for them and they get to escape. You put three on them and command denial is right out the window unless done very intelligently. I ponder attacking the zombies with 3 mace specs, while a paladin with defiance fights it upfront. 3 fighting zombies slap cranials at it while the paladin goes to town. There's ways around it even now; if we ever see 80 players and we won't, it could be very reasonable to kill even Ahtieli with some regularity.
