cross world EB ceremony attendance when?

I think its about time. the point of cross world and even cross DC is so you can socialize and play with your friends who are not in the same world / dc with you. and its supported by CWLS, CW PF, CW DF, CW PVP, etc. and yet you cant invite your friends from other world to come to your EB ceremony?

Another bad thing that comes with this is, lets say I have 30 CW friends that I want to invite to my EB, to be able to come they would need to make an alt on my world. 30 new characters on my world that's made just because they want to attend my EB feels like an unnecessary data addition for the game server. and now the game would think my world is getting more crowded than it actually is.
And theres also the hassle of having to make an alt, and attending an EB with a fresh made alt without the main character's glam collection is undesirable.

So yes. I understand and I'm fine with being able to EB with someone from the same world, but please make the EB ceremony attendance cross world, thank you!

EB being same server only doesnt even make sense. It's literally just some rooms and a cutscene.
