I cant find it, but there is a video interview of one of the Diablo developers and he basically says "We hate the pvp community".
They will take literally ZERO input from the PvP community. Blizzard has made it clear that D2 is about PvM and all content moving forward will focus on experiences for PvM players.
Keep in mind the only content that RotW has is a new character, so they will obviously make that character OP and amazing. They likely wont nerf anything until next ladder season, and it will be nerfed to PvM standards, IE so people don't dominate the ladder. Warlocks will still dominate PvP for the distant future.
@op, yes Expansion is the best spot for PvP if you want balanced public duels.
Unfortunately, lots of people are playing RotW and Ladder right now, so Expansion SCNL is pretty quiet. I think it will bounce back some in a couple months, but probably never be as active as it was. Ive been able to find duel games and if there isnt one I make one and it fills up quickly.
The problem i have is leveling, there just arent enough quality baal, chaos, cow, or TZ runs to be able to effectively level a character.
I tried starting a nightly TZ group, but my post on JSP got zero responses. The best solution I found for leveling above 95 is to piggyback off of cow runs, they take 5+ min which is enough time to clear most TZ levels and the folks doing the cow runs are usually happy to have another filler as well. Chaos and baal runs are usually to fast to be able to clear an entire TZ.
If you still have PvP characters on expansion I would highly recommend waiting a couple more months before deciding to convert anything to RotW. Also, should check out the RotW PvP scene on NL. Once Warlocks get full geared up and people develop detailed builds, they are going to be even stronger than they are now.
Just join shit baalruns and do terror zone? The quality of the baalrun really doesn’t matter
