I personally don’t have a problem with that.
I don’t think it will happen as I don’t think Bliz will invest the developmental effort into a relatively small subsection of the game, but personally think they should consider it.
I think there is an argument that this fits in the somechanges model and could increase PvP participation. You could also argue that PvP participation is lower than it was back in TBC and that this is causing unique problems.
