Do you even know which intention the lordaeron realm has? Everybody uses a 3.3.5 client. the contents are progressly released. This naxx has a buff to balance the buff the classes got with 3.3.5a. I guess the reasons for that are, that at first, the server don´t need to update the whole server with another patch. and also the community don´t need to patch their client with every release. Whats the problem with that?
the 3.3.5a is still the version of your wow-client. I can´t see, whats your problem with that. So what do you want to know? Ulduar will be released in a few months and i guess ICC, you wrathful set etc. will be released in maybe a half year? maybe 9 months? Something like that.
but i agree with you, that maybe the "lordaeron realm information" thread don´t rly show whats actually going on on this realm, which content is released and so on. And it definitly should be updated with some data.
