so honestly its very hard to take in ur question xD because u didnt state what class u playing. every class has different builds, and u can choose out of those builds.
but from what i see is that if u choose power build, then ur weapon should be power as well. it does u nothing good if u have power weapon and condi weapon in the same build.
as u say if u runnin power ranger, then berserker/marauder longbow it is
my main is power soulbeast, druid, and condi mirage. so i use berserker longbow for my soulbeast, harrier staff for my druid, and viper axe/pistol for my mirage. i dont mix different stat in one build. if its berserker then all berserker.
except for example like my condi mirage, i wanna add a lil bit of survivability in there so i add some rabid armors as well.
