That will depend on your haste, as well as a few other factors, Drizz. I usually just take note of my DF on each fight in a raid, and save setting files accordingly to quickly adjust settings for each encounter. It's a very nice feature implemented.
As far as output from this routine, I can't overstate how phenomenal it has worked for me. Only 523 ilvl w/out UVLS (Shouldn't even be demo, I know, but I can't help it! =p ) and shredding meters. Meta swapping on legendary meta gem, trinket procs, dot tracking, everything is great! And thanks for the CD toggles! Makes it that much better. 10/10. I'm currently logging parses to make generic for samples for those who want to know exact numbers, damage breakdowns, etc. I'll be posting them here when I finally have time to finish them.
This and Portal both, phenomenal. I never expected HB to get this level of PvE Routine support.
