Sure, it’s fun to see your character progress in power. But as far as pvp balance is concerned, PvP should not reward any piece of gear that improve the efficiency of your character whatsoever.
The reasoning is very simple. If you give a player who won a fight an item that increase the probabilities that he will win again in the future, it only has one effect: artificially increase the gap between good and bad players.
Ok, that requires a bit of nuance, now. There are not just two categories of players: good on the left and bad on the right. It doesn’t work like that. Without taking classes imbalances in consideration, it’s a spectrum.
At one end of the spectrum, you have players who are consistently winning and the other end of the spectrum, you have those who consistently lose. Players live somewhere on that spectrum.
If you reward winner with increased chances of winning, then what happens is that characters who were the first involved in pvp have a much higher chance of winning than the others.
It can be seen as a minor effect, but in reality, you don’t reward an athlete with steroids when he finishes on the podium.
You can argue that wow is not a sport, I’ll tell you: sure, but it’s a game.
You can argue that wow is an RPG, and i’ll tell you: sure, so it should focus on the story somehow, to keep it satisfying. But as far as instanced pvp is concerned, there is no story, only gameplay. The same gameplay since arena/BG were first introduced.
WSG hasn’t changed over 10 years. Yea, the map has changed a little bit. But if you’re telling me that, you’re just trolling. You know precisely what I mean when I say that WSG hasn’t changed. It’s still the same battle, the same concept gameplay wise, and no story whatsoever, nor any consequence story-wise or world-wise is attached to winning or losing that battle.
So, no, world of warcraft PvP is not an RPG, it’s more like quake multiplayer (deathmatch, capture the flag, etc).
Character stats should be normalized in instanced PvP. Without that, even if classes were miraculously balanced, it would still be imbalanced, and ultimately unfair.
