Yes. This is a better understanding that reflects the realities of the situation. The closest video game to 4E is something like one of the Final Fantasy Tactics games, which were from exactly that era.
And to be fair - some people at the time said this, and I didn't argue with them, because yeah, clearly there were valid similarities. And Guild Wars, 2005, was another game with similarities to 4E, and which was itself at least partially inspired by M:tG and games like Final Fantasy Tactics (even if it was real-time).
But because WoW had just added roles (in Jan 2007), when 4E came out and also had roles (Mid-2007), people immediately claimed 4E was a "copy" of WoW, or that the roles were the same (which as I've explained, they factually aren't - and they don't achieve the same things). And this kept on being used as a slur, because WoW was seen as a "dumbed-down" version of D&D that was stealing players from people's groups so they could do "dumb stuff in a video game", and people anachronistic stuff to it, saying 4E had copied stuff not even WoW at the time, or that had been in TT RPGs and video games since the 1990s or the like. It just got increasingly ridiculous (and increasingly obvious that people had either not played WoW or not played 4E or both) as time wore on.
