Rivenroad is most likely just the battlefield you fight Darnus in.

Also people seem to have overlooked this line as I haven't seen it mentioned at all in this topic yet

[dev1454] New faction leves have been added.

Possibly means that Templars etc gear is now easier to obtain.

The colleseum gear is the only real unknown from this patch... it can come from 1 of 3 spots it seems

-Skirmish (though I thought I read that the weapons would be the only rewards from skirmish)
-Legatus (But seems to be quest battle)
-New Faction Leves


Also the Caravan change is dumb, to fix people running to the end it now requires you to be in a party. This now causes MORE problems, as you can grief people by not inviting them to the party so that they won't get the seals possibly.

Also for people so concerned about not hitting mobs.... You can calm chocobo's down to restore HP. I am sure thats sufficient if you are unable to hit mobs because you cannot react fast enough.
