the title "new Horde" was originally pointed at Thrall Horde, as it has changed many things the old horde did but kept some tradition and culture, the new horde accepted allies that the old horde wouldn't think about joining them like forsaken.
but now i think blizzard is moving the horde into new era where the "new/thrall" horde is dead and a NEW horde is arising, it started with garrosh defeat and vol'jin rise to power then after Sylv become the warchife, i think now blizzard is building a Rise of the Horde 3.0 where the Orc's - troll - tauren will take step back and Forsaken and blood elf's will control, the culture of the horde will change, the base of the horde will change, and the horde will never come back to the old way's again.
good or bad i still don't know.
am i right, or i'm thinking too much about it ?
