So Blizzard seems to have a regularly occurring issue with the amount of time between the final patch and the next expansion. As a result, i've thought of perhaps a way to shorten this issue.
Blizzard has never released the beta until the expansion has been announced. However, imagine a test realm where the only thing available is the 100-102 questing zone. No names, No maps, nothing. All you can do when you log in, is to do the quests, kill things, and see how it performs. Rinse repeat this process throughout the waiting period, continuously collecting information, whilst keeping the theme quiet (obviously no big character quests. E.g. involving main antagonist. Also, should mention no quests have quest text, just find X at Y, or kill A of B.
This way, a large proportion of zones and features are tested continuously without it ALL having to be done at one time like usual, and information stays quiet.
What are your thoughts? Would this work? Do you have any ideas?
