This is absolutely not true.
There are raiders who don’t PvP, and there are PvP’ers who don’t raid, but they are not a standing majority bloc for either end of it.
Many PvE players also love PvP. It has ever been thus. Many PvPers enjoy a good raid or running dungeon content.
I would LOVE to hear an official explanation of why resilience was removed. I had a PvE set and a PvP set (as did most people who partook in both content genres), and that was never a hardship.
I like PvP stats just fine, and I like the idea of PvP gear being made available for those who focus PvP over PvE, and I like that gear being better for PvP than PvE gear. The balance, however, is a fine line, and that’s likely at the root of why PvP stats were removed.
Still. I’d like to hear the particulars and understand why. I don’t understand the communication allergy Blizzard so often has, and I’m grateful they’ve been more forthcoming about Shadowlands. I hope the information/communication gate stays open.
