Testing Server Access for all raiding guilds

I will refer to my post in this thread: viewtopic.php?f=2&t=13439&start=10
Just wanna tell my opinion regarding the players that get access to the testrealm. With a server that supports 8k players I think it wouldnt hurt to allow every raidguild to test the raidcontent. Right now several guilds are being shut out and the guilds with access does gain an unintended advantage when it comes to progression. Once BWL is released the guilds that ran it on the testrealm know what works and what doesn't. Just look at MC atm, it has some bugs which can cause wipes because the script isnt working properly.
I'll also refer to how it was in retail, where everyone could access the testrealm. However, I don't think its reasonable to allow every single player onto the testrealm but I atleast think it would be reasonable to allow every raiding guild to test out the content in order to promote a healthy competition among the guilds.
