Concerning Guildmarks and Leves...

[Aeyis]

I've yet to complete the rank 30 quest for my con, but all my mark leves shifted to the rank 40's some time ago.
Also i believe the ranks at which you can get marks as reward for a class, equals the ranks at which you can obtain higher rank leves. which would be 13,23, etc. (i think? )

At any rate, if you can get the rank 30's to give you marks instead its a better deal for you anyway, since higher rank tends to give a lot more marks as reward. ~
