I'd also like to have such system implemented.
I tried to play this 3rd season as much as I could, but could not spend as much time as other players and the PVP score gap kept increasing as the days passed...
Now I'm sad knowing I spent time trying to get to the top but not as much compared to the others to fill the score gap.
I understand that the top players want to keep their exclusive stuff, but it could be great if for exemple we had tokens to buy the last season's stuff.
And each time the current season winners would have their exclusive stuff meanwhile the others can spend tokens accumulated for previous season's stuff,
to not make the time spent in pvp feel like wasted.
