Archetypes

[Nihilarian]

Keep in mind that if you critical while using Rough Divide, no matter how high your attack roll is, you're dealing normal damage + critical effects. There are ways of getting neat effects to those critical hits, but unlike the "max damage criticals" Vil used to have you don't automatically bypass DR or anything like that. And ultimately, you're relying on a coinflip at best, specializing in criticals (and you still have to confirm). Now, the limit break changes things, but that's a limit break. It's supposed to. For the rest of the time, you're giving up some things and getting other things. You have the option of specializing, and it can make a pretty good character, but they'll cost you (whether feats, class levels or gil). I don't think that's unreasonable. Am I underrating criticals?

I'm not sold on the name of the ability. It doesn't really have anything to do with Limit Breaks. Anyway, you are spending bullets while using this ability due to the Trigger ability.

for the other archetypes: How would you feel if the "Holy Dragoon" was an Archetype of the Holy Knight class, rather than the dragoon? Giving up some defensive abilities for the dragoons jumping abilities?

I'd have to do some research on the Dragon Knight class. The Mounted Dragoon might be an archetype more fit for the Chocobo Knight. Although spreading out who gets animal companions/mounts might not be a bad idea in and of itself.

Feel free to make any suggestions on how to improve these archetypes, as well as future archetypes.
