What is the point of this Thread anyway? You're starting off with the "I understand why people love TBC" and following it up with a "But," and then lists the reasons why you don't want to let people have what they love because you don't want it? You got Vanilla, now you want more? Vanilla not good enough? You want an entire different, alternate universe?
Vanilla vs TBC comes down to subjective taste, you got what you wanted, you got Vanilla, let TBC players have their TBC servers if it gets to that.
