pvp stat prioity
Short Answer: Yes
Long Answer: Yes if you’re running a power build.
in pvp the sigil and runes ARE your stats because all armor and weapon have the same stats .
in WvW you want to stack power/precision/Ferocity but imo you may want to add a bit of toughness .
I hope you know that PvE stats do not matetr in PvP so “stacking” berserker gear is pointless and a waste of gold and time. Every stat is in the PvP amulet. I’m pretty sure the guides you saw listed the amulet you just did not know that holds all the stats.
