Um what 2 kings have died in game? I only know of ONE and he died an extremely heroic death in the same fight where the Horde lost their leader to some unnamed rando demon's poison when Trolls are supposed to be immune to poisons or some shit. If you're implying that Anduin is one of the "lost kings" he's not dead and will return to the Alliance at the end of this expansion almost guaranteed while the Horde will more than likely lose yet ANOTHER major lore figure (and former Warchief and former leader of the Forsaken)
Exactly what road are you talking about that was added to the Horde for players not to get lost? Been playing from vanilla and the only changes to the layout of the map for Horde was to bring the starting cave closer because it was further away than the Alliance's starting cave.
Care to share where you got this information especially since the Vulpera were introduced to the game with the launch of BFA while the goblins weren't introduced into one of the last patches.
Alliance racials were the OP ones in both PvE and PvP for a very long time. Namely the human racials starting with vanilla and continuing even to this day but was made even stronger when Every Man For Himself first was introduced. Night Elf racials are another OP one as it gives them a way of dropping combat and making their enemy drop targeting them which is OP as fuck in PvP. There's a reason why every player in the MDI crap is Alliance. Its because the racials are the best in PvE contrary to what YOU happen to believe. Even if the players are normally Horde when they play in game, they are Alliance when they are in the tournaments.
