I have been using BRW instead of PP
my guild does 25 second countdown so my opener is
20 seconds before pull pop BRW so that it is back at apocalypse intervals, this allows me to repop BRW at :40 second mark and 1:40 second mark so it gets to line up with apocalypse doing this means means i always have 6 wounds 0:245 second into the pull while only using 1 FS, also get 4 BRW casts in a 3:25 second goroth fight so that saves me 20-23 runes and PP only restores 11 runes at best in that same duration.
openner
+0:20 BRW ---> +0:07 Army --->+0:02 pre-pot/Outbreak ---> FS --->bloodfury/gnawedthumb ring --->Chains ---> Apoc ---> DA+Fel-oiled machine ---> DC --->DC ---> DT ---> DC --- begin weaving in SS and DCs
as Orc with gnawed ring i have to get the first chains + Apoc 6 wound burst out with those buffs running and only the begining casts of DA, with BRW after my initial RP dump im usually sitting on 5-6 wounds and 5 runes (this is with Shadow infusion not Infected claws)
