Just like @EfficientNinja said, Battle Royale style has taken over. That is almost what everyone is playing right now.
Wow is a trash game.. I'm not sure why people still playing this shit Sent from my LG-H870 using Tapatalk
World of Warcraft has been in decline indeed. But let's be honest, World of Warcraft is still popular enough to sustain itself.
I see each year the game is dying. You can clearly see people are moving towards the pubg. Not even minecraft is being played now.
Minecraft unlike WoW is now more popular as a private server sort of thing. A run between the people who know each other. World of Warcraft isn't destined to die, even if it declines in population it will stay, as it already surpassed numerous mmos.
