Would be cool if PvP series was expanded to PvE

Yes add another one and call it PvE Series, i would love it, it gives me more to grind

Pretty much what I was thinking. I'm cool with this idea as long as the rewards are different than the PvP Series.

PvP Series rewards should stay unique and specific to PvP; and, if PvE Series is implemented, it should have its own rewards that nothing else has access to as well.

new different exclusive series would only exacerbate the issue OP underlined, it would push even more people to do content they don't enjoy because they want the reward, that's simply not healthy, a general track you can progress by doing varied things within the game would naturally fill and add extra incentives for playing the parts of the game you already enjoy
