I agree with the sentiment that ‘now is the time to strike’ (not even because of reasons you mentioned from external forces but I like where your head is at 
)
As Bliz does NOT have a very good track record of making game play /fun improvements via QoL (like LFR, and Boosts, etc) I defer to the #nochanges narrative. I 1000% agree we need a FRESH but for reasons of: Cost, Simplicity, drama in the company; it’s best to simply relaunch what they already have exactly as it is now with the caveat THIS SERVER WILL NEVER PROGRESS! A ‘Forever’ Server. I made a post feel free to check it out.
