The Elder Scrolls Online "Ask Us Anything", Roleplaying Edition

Rather than go for a nondescript-but-numbered approach in the latest "Ask Us Anything" to hit The Elder Scrolls Online website, the team at ZeniMax has devoted this latest Q&A-filled entry to role-playing as it applies to an MMORPG. A few questions and their answers:
Will the megaservers dedicated to PC/Mac players be one megaserver for the US and one for the EU, or will it be one megaserver worldwide? Our community is worried that the friends they have made from either side of the pond won't be seen on their server.

We do plan on having one megaserver located in the US and one in Europe for PC and Mac players, but you won't be forced onto one or the other. You'll be able to play with your friends, but it's important to note that you may encounter higher latency if you choose to play on a distant server.

...

We know we'll get cross-faction chat through guilds, but will there be anywhere that all factions can congregate and communicate? Like is there anywhere in-game an Ebonheart character could unfortunately share a mead with a Daggerfall character (you know we roleplayers enjoy conflict)? Can these characters group together if they are in the same guild?

Though we haven't implemented areas expressly for this purpose, there's nothing stopping you from sharing a peaceful (if tense) round of drinks with characters from another alliance in Cyrodiil except maybe their allies! Though you can't group together if you're from different alliances, many of our social systems are focused on you as opposed to on your characters individually, and you'll be able to communicate across alliances through these systems.

...

What will the weather be like in ESO? Will it always be the same or will it change? Will we see a day/night cycle?

From snowstorms in Skyrim to rain showers over the moors of Glenumbra, you'll experience lots of weather as you explore through the day and night in ESO.
