wedding cut scene

[kyuven]

Also, there is great fun to be had watching you solo T9 when you rewatch the CS.

As a WEAVER!

Again, I don't see anything wrong with it. I've rewatched the BLM quests cutscenes as Leatherworker, and even the NPC's dialogue changed accordingly: "One moment, leatherworker."

In addition to what was mentioned about you marrying nobody, the wedding cutscenes also use your guests. So you'd be marrying nobody dressed in your adventuring gear in a room full of nobody.
The only proper solution is an actual recording of the scene, which would utilize different software than is currently used.
So yes, in order to record your wedding they would have to tack on more software to the client. PC and PS4 users CAN already do this, though it's tricky for the latter.
