I’m curious about Delves, holding out judgement on those.
I’m unenthused about Earthen, but there is a slim chance their story will win me over so can’t write that off yet.
Warbands are a QoL feature and not really content, they will be nice to have but not really a new thing to do, per se.
Hero talents are just more talents, nice to have but not really a new thing.
I think they said they’re adding a new BG? That will be nice for pvp players.
I think that is everything they’ve announced, aside from the new zones themselves. But I’m sure others can add anything I’ve missed.
