This dude is referring to elite four cool down and Shedinja nerf I think. Forget it dude, it won't be returning again.
Yes PvP players are finally enjoying them, why not just try PvP and enjoy it yourself. No one is forcing you to stay PvE oriented, we're in a MMO, you should try every features of it. Play randoms it's really fun and frustrating sometimes lol
PvE is also gonna get halloween in this month and PvP players will also play it, it's not like they just stick with PvP, most of them do both. I suggest you to add more suggestions and discussions about PvE contents and not to hate the PvP oriented updates. PvP players have asked the updates for a Long time and now they're finally getting them.
