Post AoS (I forget how long ago), more weapon properties were added. Namely I am speaking of mana drain & hit fatigue (stamina drain). In another thread I discussed the stamina drain of some mastery skills & the conclusion was they were worthless against the paragons you really needed them to work against (namely paragon balrons and equivalent from the treasures events). So are there any events / mobs worth using mana drain or hit fatigue on and make a real difference? Maybe mondains legacy peerless?
