How are Zeros at bossing Compared to Paliadins?

Well, since scissors are on sale tomorrow, I was considering scissoring all my warrior gear onto my zero. As you can see by the title, my current class is paladin.

I was just wondering how well do Zero's do at bossing? As a paladin, I can pretty much stomp at most bosses due to threaten cutting defense essentially in half and void elemental making any damage lost at bosses by their passive phsyical def basically nothing [seriously OP skill...]

I was just wondering if I would actually be weaker by transferring all my equips to my zero. If that is true, there's not really any point.

Also general opinions on how Zero's boss would be nice. Also people's damage with ranges against bosses would help a ton! [with str % and att in status window please]

Thanks~
