Why do long time players play the game so differently?

fair enough, but they are trying to come across as a "new" player that came with the wave last year...

which zero facts back up. so, basically, just a displaced troll if anything

I don't disagree with how they present themselves. Merely just pointed out for you there were previous exodus of WoW players into other games, its just with Shadowlands it made headlines in comparison.
