High pop server opinions?

Hello all,

Horde here, and I've been looking at moving servers to actually find people to play this game with again. I will only be doing PvE stuff (that being said, I don't care about if the server is PvP or not). And while I won't be raiding right now, I would like to position myself on a realm with decent progression in case I do take up progression raiding in the future again, so that I don't have to transfer servers again anytime soon.

I've been mainly eyeing Area 52, Blackrock, and Mal'ganis (even though they just lost Exodus). Illidan possibly as well, if they don't have enormous queues at peak times. I fear they might.

I was just wondering if anybody plays on any of those realms and what their experience on the realm has been as of late. Or, if you have any opinions in general about them. Or, if you want to convince me that another server may meet my needs better.

Thanks!
