Which server does Batman play onFollow

I keep seeing these ads offering to show you how to hit level 85 in four days. Now, I think I'm getting relatively proficient, but come on?!?

In order to solve my server/guild issues, I just started over, same class and race, different server (and this time got picked up by what looks like a really good guild). I figured, what the heck, I'll zoom right back up to level 75 in no time and be happier in the end. I play a lot, but its been all I could do to hit level 46 in seven days.

So, my question is - and since I obviously believe everything I read in spam ads - which server do Superman an Batman play on?

The last two characters I've taken from 1-85 have taken less than 4 days of playtime. Both of them had 4 pieces of BoA gear and had guild xp bonus so I was sitting at 45% xp bonus. I quested the whole way while grinding dungeons and each toon made enough gold with gathering professions (which also gave xp bonuses) to buy all levels of mounted travel (over 10k gathered on each toon). I did some socializing on each and spent some time on pvp.

I haven't used any guides but I have a pretty good memory and remember which areas give the most xp (stonetalon mountains is a great area at low levels).
