Mind telling me where that 80% comes from? Or are you just letting your subhuman mouth run? Your reply has no sense on regards of the topic, you just came here to flame someone who is trying to provide his experience.

There was a bigger player pool if we talk about the total population Wotlk had back then in retail, but when it comes to realms, Warmane realms are almost-equally (
http://forums.mmorpg.com/discussion/...op-of-a-server) populated and have a bigger 80s player pool and obviously are way more geared than what retail wotlk realms used to be.
But, I can say for sure that people in Retail put a lot more effort into raids. There in Retail, people choses what to play and it all comes to what kind of realm you're playing on, on most PvE servers it was absolutely normal to get to down Sindragosa on a normal pug. People even used to get into Ventrilo and coordinate each boss fight and even get to know more people, meanwhile here in Warmane people doesn't care about logging into RaidCall or TeamSpeak or whatever program you're using, and if you make those guys get into those channels you either get bots who don't say anything (and sometimes don't even listen anything) or *****s who aren't even part of that raid to "troll" around (and most of the times end up insulting everybody when they get called out).
TL;DR; I have no idea if they keep putting that much effort into downing bosses in retail, because you know, LFR... But I can say for sure it was how most of raids used to run till Cataclysm (Which was the time when I stopped playing).
TL;DR2; I used to love Retail pugs, it was truly a mmorpg experience.
