The job restriction "makes sense" in that it gets people to play other jobs. But it also sucks, cause good luck getting DRG cards. PUP cards. MNK cards. etc.
If you didn't lock cards to jobs, everyone would just pet zerg every boss.
Middle ground is exceedingly small.
10:1 is INSANE though.
I will say this though, some of the gear is totally legit, but most of it is meh at best. 20 hour locking it, and making it take 20 days per piece of +3 is pretty disgusting.
