PvP player perspective on why PvP players kill friendly "questers" / PvE geared players.
I Have Been following the post on this sub since the beginning of this event. And I have seen a lot of posts from PvE players who obviously do not enjoy PvP tired of getting killed when just trying to do activities for the event. The counter you see is from other players pointing out that PvP zones are for PvP. But I think the problem is more nuanced than presented here. I think it's the easiest to explain with my own anecdote of killing questers in Vlastarus.
Day one of the event I decided to do all the golden pursuits as I never know how much I was going to play. At 10 in the evening I am just missing the Quest in the towns. At this point, I have already decided I am not going to kill anyone I just want the quest over and done with. But I decided to take my magicka sorcerer as an insurance as this is by far the best 1vX class in the game. Plus it also has good damage for the few PvE enemies during the quest. Once I get into Cyrodill none of the towns are AD, but I decide to go to Vlastarus anyway as we control a few keeps there. When I arrive there are 6-7 blue players, a quick glance at their HP, as well as none of them keeping up buffs tells me they are all there to quest and I run past all of them without attacking a single one. Once I pick up my set and quest and head out I run into a Warden player whom I have killed a few times today already (In IC and in keeps). He's not going to let me go, so he obviously attacked me on sight. This wouldn't have been a problem for me, but the second that he attacked me… Every single one of those players that I just let live decides to join him. I end up spending the next half an hour kiting and picking off this group of “questers” across half of Tamriel. And all that time I couldn't help myself thinking that if I had just killed them all at the very start they probably would have returned to base and I would have had the town for myself.
While this might just be my anecdote, when I talk to other players the number one reason that they kill “questers” on sight is that they hate being 3rd partyed. PvE templar beams, lightning heavies, and snipe spam are the most infamous.
From a PvP player to players that just want to be left alone. Stop 3rd partying PvP players at every opportunity you get. While you're never going to stop the Nightblade gankers who are having the time of their lives ruining your day. I feel like I have pretty much been “radicalized” into killing PvE spec players on sight. I can not think of a single time recently where I let a PvE player live, and that they didn't attack me as soon as they saw an opportunity to do so. PvP players aren't so unique evil entities out to ruin your day, most of them are looking to have fun and typically these are near-peer 1v1 2v2s with other PvP geared players. And when you interfere in those fights you ruin their experience, and this is why they kill you, even preemptively. Most PvP players don't take joy in killing questers, they do so because they know that these players won't think twice about 3rd partying as soon as they turn your back on them.
