Someone in full PvP gear will stomp someone in full raid gear tho… the PvE gear will have far less versa and so they will take a lot more damage.
The only way a PvE geared person is “stomping” in bgs is if the enemy is all undergeared.
It’s stupid fast to get fully PvP geared right now, between crate farms, the free 9 crafting tokens, the free weapons from the feat of strength and bloody token gear to fill gaps, it takes like a day from hitting 80 to be in full PvP purple gear. And no one in raid gear is stomping you then, at least not because of their gear.
The only PvE gear that is bis for PvP this season is the cloak, which is an hour long quest chain to get and its all account wide so it’s free and instant to get on alts, not a big grind at all.
