Idk what the regional offices do tbh. Probably just like translations?
No, idea, but all I know is that a lot of news content is either never posted on EUNE or vastly delayed.

^ that one, for example - we never got that page on EU. At all. So had I known about it, I'd bought the Fizz icon. But Dorito doesn't want to even acknowledge that mistake, much less make amends for it.
I posted a notification about that fact to a Rioter, but only got some generic, nonsensical reply back.
And here I have another joke for you:
Regarding translations, I have heard this argument (also made by someone from the EUNE news comment section) over the reason for content taking such a long time to get from NA to EUNE: it doesn't get to the [English] page because it have to be translated first.
I mean, translated from what? American? I haven't heard the argument "American is not English [British]" - and that from an English-teacher no less - since high-school. xD
There are indeed valid arguments to move to NA (cannot post in the NA news section when from EUNE), as there seems to be both more Red activity here as well as less stupidity, but my ingame ping would then get FUBAR ("rekt", to use LoL terminology). :'(
If the ingame ping on the NA server would be same as on the PBE server when playing from my location, I wouldn't get less than 200ms (tested on a 700Mbps connection). And thats kinda...ouch.
