30 sec cooldown for Mushroom planting (and Efflorescence)

Routine should be very careful while planting in WoD.
chrykoolaid, Mirabis is(/was) going to continue in WoD, but you should understand that HB will be updated only in some weeks, after that some time for testing is needed, noone will know optimal rotation yet, ofc no encounter specific functions for a while, a lot of hotfixes from blizzard on start (= HB downtime = no testing), Christmas..
So it will be updated but not instantly

I think you'll have a couple of months to take a rest
