I'm genuinely curious so I have to ask, I've done retail 99% of my WoW life since beta and only endeavored recently (lets say a year ago) into private servers looking for that Vanilla taste back. I've had a character done on wow rebirth server, which was deserted and has been shut down and more recently on ED from feenix.
So my question is; what's so terrible about those other private servers? I'm not into the whole private server thing so they seem fine from my stand point, but I haven't delved deep into raiding on them so I must be missing something that seems blatantly obvious to you, more savvy people, of the private scene.
