Oh yeah, if there's any job that should have resist paralyze, it's DNC.
In fact, it should get resist amnesia too.
I mean think about it. Paralyze isn't a very big problem for mages, as they can spam paralyna very fast. DNC however, can only use healing waltz once every 15 seconds, and even if your attempt to use Healing Waltz doesn't get eaten by paralyze, it might still cure a different status ailment than the paralyze you wanted to get rid of. To add more suck to this, while trying to get rid of paralyze, you also cannot restore your HP, because that's on the same timer as healing waltz. Additionally, attempting to heal several status ailments on several party members takes forever, but that's what I would hope to solve by splitting timers and/or adding more potent healing waltzes.
As for Amnesia, SCH and BRD gets resist silence to help avoid getting shut down. Amnesia destroys DNC's ability to heal, buff and debuff the enemy, and there is no realistic way to get rid of it either, unlike Silence which can be cured by cheap echo drops. I mean sure, there is Ecphoria Ring, but that's a 30 second wait after swapping into it before you can even use it. Resist Amnesia just makes sense for a dancer.
