Our current cast of leading characters is truly pathetic. They are underdeveloped, underused, underpowered and lack any sorts of investment that could draw a horde player emotionally to them. To fix these issues it is needed that the horde council gets replaced with characters that could actually stand off against the big alliance super heroes.
Orcs - kill Thrall. Bring back AU Grommash
Trolls - Rastakhan and Jindo the Breaker
Tauren - Sark Ragetotem
Blood elves - kael’thas Sunstrider
Nightborne - Grand magistrix Elisande
Undead - sylvanas can come back.
Then the horde would be fixed.
