The whole world has changed, along with 90-odd% off all quests - it's no major suprise for me to discover that the updates on Wowhead aren't fully current as yet. There is a lot of data to update.
SWC isn't exactly dead. I find it to be quite a vibrant community to be honest.
Being an RPG server doesnt seem to have a major impact on names, however I'm certainly no expert and depending what it is will/may dictate whether or not you have to change it in the future.
If you went in thinking its going to be the same as 2 years ago, it's not.
