Classes after big bang

Dunno if you guys have seen these vids but I was looking through youtube the other day and came across em. I didnt bother looking through CK classes. And these vids are mainly from classes lvled 140+, 4th job and unders no fun. . .I tried to get em from lvl 140-150 but some just arent there. From what I read from the comments all classes get a passive 5% crit rate with 20% min damage and 50% max thats why crits are all over the place. I suck at those spoiler things so if a mod can do it for me uh yea it'd be easier for everyone.
