I am really hyped about the news for opening a TBC realm as like many others I guess, so here are some suggestions for the upcoming Outland:
1. I really want to see x1 tbc realm(like many others here), but I am fine with x5 as far as goes for the shop.It woulbe nice if you can make the shop like in Lordaeron.What is the point of progression if someone levels up to 70 and buy all items that are BiS at that parcticular moment.
2. The shop can include mounts, pets, tabards etc.., but putting the best items that the game can deliver to players or even legenderies is something that no classic TBC player wants to see.The realm will be successfull as what most of the comunity here suggests.
3. It will be even perfect if you find a way to implement a dual spec and achievments.(these are the two, that I mostly want to have when I play TBC).
4. A lot of players feel really nostalgic that they will be bring back 10-12 years, so listen to them and make it a real progression realm(first T4, T5, T6, Sunwell) and a lot of players will come to play and all of us staff and players will be very happy.
