I’ve almost got all of my 24 (one for each dps spec and race) toons to 60.
Should I just wait a year for TWW to release?
I was originally going to purchase Dragonflight and was waiting for it to drop in price after another xpac release but it seems they bundled it with the new one this time. 
The expansion isn’t going to drop unless they have a sale…which given they are preordering now and bundling might happen but unlikely. You are better off just buying the preorder
War Within pre-order comes with DF, iirc.
You can buy dragon flight for 30USD
For 20 more bucks you can preorder TWW and get DF and the ability to play TWW if you want.
Yeah that’s crazy cause I finally found the separate price and as Anadisong said, it’s $30 for Dragonflight ($50 for TWW with DF).
