CotH isn't a totally "Blizz-like" server. However, it also doesn't have absurdly increased rates.

Ruleset: RP (though toggling /pvp will activate an FFA flag)

Some differing specs than normal:
5x XP Rate.
10x Quest XP Rate
5x Rest XP Rate
10x Money Drop Rate
2.5x Green Drop Rate
2x Blue Drop Rate
1.5x Purple Drop Rate

2.5x Skill Increase Rate

Despite the name of the server, Alliance characters are also welcome. I haven't had Alliance outposts or cities taken over by the Horde or anything.
Admittedly, most of what I add by ways of extra NPCs or items to vendors will first be done in Orgrimmar, however I also seek to outfit Stormwind in a generally-similar manner.

In addition, all characters can speak Common/Orcish. After all, everyone was able to talk to each other before WoW, and the language barrier was added simply due to the MMO setting (ie, preventing gankers from easily cussing each other out). Furthermore, custom emotes will indeed be seen cross-faction, so don't worry about needing to 'emote in says,' so to speak.
