Ahem, anyway, TBC is a good, since some people seems to prefer that rather than vanilla or wotlk,. Doesn't seem like Warmane will do another expansion though, at least not for a long time
In my opinion if expansions are going to be added to Warmane we should go backwards not forwards. They can make The Burning Crusade and then maybe even Vanilla. These days many WoW players miss their old days so old expansions are getting very popular.
TBC, because that's the only expansion that basically has 0 servers with 1000+ population. It's like a big sweet fruit just waiting to be eaten. And it seems to me that porting content to Tbc from Wotlk would be much easier than to Cata for example (i might be wrong, though).
How about we get all the **** that's ****ed up with the current servers fixed first, before we go off and make another? When every single quest, spell, raid, ability, item, etc. is working, then start up work on a 2.4.3 server.
They never have to upgrade. The server will always be locked in at the last WOTLK and Cata and MOP patch, so there's zero reason not to fix every single thing there, then put all the focus on TBC. I'd rather them spend 2 years bug fixing and launching a TBC server that can see weekly, or even daily, updates fixing all the bugs that won't show up until people actually get on it.
And don't allow people to buy gear either - its what's caused so many problems on Icecrown.
