Quite true wrt disease spells. The other thing is that SK can attack several resists, while paladins can only attack magic resist. So the burden of casting Audacity (and getting and using weapons that proc Tash and Malo) is much higher of a requirement for paladins. I think it's a neat design by the Devs to create beneficial ToT spells like Protective that enable niches for e.g. paladins to tank mobs that resist like crazy. I would like to see more of these types of spells that cast quickly and do useful target of target healing and buffs (temp HP, runes, steely blades, defensive procs, AC, swarm pets ("the cavalry has arrived to protected SoAndSo!"). Similar to SK Theft and Torrent spells in their application. ps: SK does have one old spell that lowers all resists by -10, Aura of Darkness, that probably goes unused because the lures on mainline spells are plenty good.
