No bnet data but there are about 6-9x as many d2jsp users using the trade forums for RotW SCNL compared to Expansion SCNL.
PvM is dead on expansion. No Baal, chaos, cow or TZ runs anymore. If you can actually find a game its rarely full so getting P8 exp is hard.
Duel games are still common on expansion. It seems like the PvP community is the last of the hold outs on expansion. Which makes sense due to serious concerns of the warlock being over powered.
Eventually I think everyone will switch to RotW just like everyone switch to LOD back in the early 2000s, and everyone switch to D2R when it came out.
I’m still on expansion, but as the weeks go by it’s become obvious that expansion is dead and I will have to convert if I want to find competitive duels or be able to lvl my character from 99. I run into a lot of the same players which means the community is a fraction of what it was pre-RotW.
Thanks for your detailed opinion
