I for my part, think that the team should look into competing with something else than some strict adherence to some special snowflake "more blizzlike than blizzard" formula, since the worst extremists have other servers to go nowadays. We should keep being blizzlike in preserving the atmosphere and cultural treasure this world is, but some custom content that are just vanity or enhances RP:ing (a mature, adult playerbase that 'B' has always but ignored) would be welcome. One example would be the opportunity to gain rep with the Scarlet Crusade in a manner similar to the Bloodsails (ie. by grinding Argent Dawns, for Alliance only ofc.). Another nice thing that could potentially draw a lot of revenue, especially after TBC is released, is the chance to pay for the opportunity to play as a High elf. Which would only be a cosmetic thing, a blood elf with exactly the same abilities but with blue eyes, on alliance starting in Elwynn like humans (you could have Dark Irons as a Horde equivalent.. maybe). Some other stuff that wouldn't break immersion nor be a heavy burden on people's potatoes - like new models - could also be a nice change.
Community does matter. For my own part - and I really had nothing to do with the stuff that took place - I was digsuisted to see 4chan trolls come and viciously attack people who have worked their backs off for years out of love for this community and the project. Surely a lot of those probably don't even play the game and was drawn there by neo-nazi propaganda videos on youtube - but it still kinda made me despair about the future of this community which used to be known for its adult playerbase and seeking to preserve some kind of immaterial values. Community matters and people matters. People are DM:ing me on Discord and telling that they wouldn't wanna play without Shenna, for example. The major reason for why this project have been at a disadvantage compared to the hackers is because they shut down our severs and also torched them purposely so that only they could offer people's toons with all of their character progression up to that point.
For my own part, I'm eagerly awaiting TBC - but I could already have gone playing on one of the already TBC servers. Community matters - and we should be able to compete well there through actually holding up the legacy banner of attracting the mature, adult playerbase that do not engage in petty drama, trolling or hacker attacks. That kind of community will always have a given segment of potential new players especially as people grow older.
