This can't be an echo chamber
Echo chamber is created when an individual refute an opinion without any consideration of what credential it entails. A.D.Grape disagrees with me often, so I don't see what echo chamber is there.
Many many people want more PvP just not the flavour doled out by the current mess, but rather than join in with all the other players in a way that means we can stop this PvPvsPvE argument instead everyone else is generally told they're wrong, they're not fit to have an opinion and probably a scaredy that'll run to solo and combat log.
Slippery slope, just because people make conclusions based on questionable premise doesn't deem them to necessary have to "run off into solo and combat log."
It's not productive.
It's not productive when conclusions are being drawn on misinformed or haphazard premises.
