I’ve been a Single-Player since Early Access, but I’ve been around the forums for a long time now. And if memory serves me, PvPers have always complained. Always.
I recently finished reading Daniel Kahneman’s book Thinking, Fast and Slow where the author describes (among other things) the differences between the experiencing self (ie. the me who is writing this post right now) and the remembering self (ie. the me who thinks about this moment later in life). I very much recommend that book to everyone who wants to understand how the human mind (including their own) works.
