Okay so before the update, I don't really think "the one who had the better armor and the better sword" really made that much of a difference in pvp. There were many times that someone killed me but I had the better armor and the better sword. I was kind of disappointed but it wasn't that big of a deal so I usually would then go on creative or do something else. I used to play a lot of hunger games and eventually I learned that I was much better at sneaking up on someone when they least expect it and killing them. That way was much more simple.
Now, the update made it so if I sneak up on someone they just run away all the time and it is the most annoying thing ever. I still think that it would just be nice if they got rid of cool down because then you could get more damage done and also block the other player's moves with a shield. That way it isn't as time consuming plus it still requires skill with attacking and blocking at the right time.
