This is just stupid.
Before the Pserver population exploded 3k at peak time was amazing for a blizz-like x1 rates realm of any expansion, average being like 500-700 on each faction and the server was in a healthy state. Whining about a population hitting 1,200 with a 50/50 H/A ratio (as Zeth'kur has) is extremely ignorant to the reality of what a healthy WoW population is.
And Elysium has had 7k+ players online today (Thursday) with a H/A ratio of 50/50 (more or less) so what exactly are you bitching about? That you can actually complete a drop quest without having to compete with 200 others players at the same time? Poor baby.
Furthermore, Zeth'kur provides the same content/patching as Elysium without the bloated population which is what some people prefer.
Now that the quality of these servers have increased, drastically, and are attracting thousands of players you new guys want to freak out every time the population drops. Most people aren't going to stick around and play this game non-stop all year long. It's unrealistic to think the population of any realm will remain a static number after the current content gets old; noting that the population will again spike as new content is released. Here's a TLDR link to all the population/ratio/zone stats you'll ever need for Elysium: http://vanillaradar.com/elysium-stats/elysium/
Now shut up already.
