I think the new public realm chat is pretty damn cool. Reminds me a lot of, well, other MMOs. (World of Warcraft Barren's chat flashbacks)
However.... Haven and Hearth isn't like other MMOs. The realm chat goes as far as realms can stretch, and frankly, they can stretch pretty far, and not everyone who is in a realm border is exactly a part of the realm. Often they are just mooching off the buffs.
I can't help but feel this somewhat hurts the feeling of "loneliness" on the game. Playing for your first time you can often find yourself pretty damn alone. Whenever you come across another player, it's scary, are they friend or foe? Will they follow me? It's an experience that isn't easily replicated in other games.
I think there should be some type of requirement to be able to have access to a realm's public chat. A skill? Or perhaps an item that's consumed to show that you are more "civilized" and can communicate with hundreds of people simultaneously screaming at each other hundreds of miles away.
Yea you CAN just ignore it, but it's always going to be there, and you know, watching, right in the corner of your eye.
It doesn't make sense in terms of the Haven of Hearth's rough "lore". I can get communicating if you've "kinned" someone before, but here there's little excuse outside "you're in a realm".
Give a month or two and a new world will be covered in Realm claims. Every active looking place will be claimed.
