I'm sure that this will be explored in your survey which I'll do, but my main feedback would be that I don't think most people are opposed to PvP updates in general.
However, I think people are getting sick of being told that x new PvE encounter is a PvP update just because it's being released in the Wilderness. PvM is one of the most popular aspects of this game. If you release a new boss, people will want to kill it regardless of where it is. And a big portion of those people will be frustrated by interruptions from people looking to engage in PvP that they aren't interested in.
I've finished every wilderness boss, and I while I didn't hate every second, overall it would have been more fun for me if wasn't in the wilderness. You need to find a way to get people who actually want to fight each other together that doesn't involve an unwilling third party.
