I love Wow Gold and Wow Power level

It seems to come up quite often. Someone wants the language barrier bought down. Even if it requires questing or skilling up, they want to be able to talk to the other faction. It would even make lore sense, since at the least, Undead and Blood Elves should probably know common, and Thalassian is probably close enough to Darnassian that someone who knows one language should probably be able to get the gist of the other. That said, Blizzard's held pretty fast to the principle of squelching cross-factional communication. The only way you can make yourself known to the other side is with the default emotes, or sometimes with a bit of creative typing that can only convey crude messages.

PvE: You won't get any 'accidental' Player vs Player action. This does make the world safer, but might also take away from some of the excitement when moving into a contested zone. Some people argue it might be a smart choice to start here initially as it will let you get a taste of the game first without getting 'disturbed' by evil (Allies/Horde). PvP: The gaming experience can be much more intense when you see that dreaded "The Zone You're In/Heading To Is Under Attack" pop up in your chatlog. However, truth be told, both sides have a fairly safe leveling zone for the first 20 or so levels, meaning you won't instantly run into lvl 60 characters trying to take down the newbies. Battlegrounds tend to be more active on these server as well, but that's a fairly generic sweeping statement which needn't necessarily hold true. RP: Use either the PvE or the PvP rule-set. Tends to draw a slightly more mature crowd and you might even find some actual Roleplaying. Note, Lewtwhore, Roflcopter or a similar name will likely get you reported on a server of this kind.
