No racials these days are not really relevant
No racials these days are not really relevant unless WOW TBC Classic Gold you’re super min maxing to gain a 0.5% advantage. He’s probably referencing the fact allies feel that they’re constantly shafted in the legends (taking more losses than Horde and the like).
A significant portion of the player base is in fact horde as that’s the case for the most of the major guilds that raid (unless you’re oceanic, which is the reverse).
Meta > Friends > Lore. There are many excuses they like for the faction they pick, however when you arrive at what you actually have to say at the top , it’s because players were following the meta, while one faction was usually superior in PvP. They should have disabled race-based skills for the factions that play PvP prior to when the game was released to ensure that the imbalance wouldn’t been as dire.
When the game was released, the very best players/guilds in successful MMOs were focused on PvE (some instances). For PvE as a whole the racial abilities had smaller impact than the overall impact of Paladin/Shaman talking about 40 players. In this case, the game’s meta is Alliance. Everyone is familiar with PvE, and they can do it at the comfort of their own bed. There are hundreds of videos and guides to provide the full explanation of each. The most difficult part of the game today is the PvP. In smaller group games there is a difference between Shamans and Paladins might not be as significant but the differences between racial groups are very obvious… Horde is now the meta faction.
The idea that one side is made up of “better players” than the other is completely absurd. Consider the steps needed to buy TBC Classic Gold select one side over the other, there is practically nothing that obstructs someone from being able to pick one or the other.
