Are you all really arguing over such silly semantics? End game is end game. Who cares what it is called. Swtor raids were called operations and they were all 8m/16m content. FFXIV has coil/trials/CT etc...End game exists. Doesn't have to be called a "raid."

With that said, anything more than 16 people imo is incredibly boring. I prefer to smaller groups with more focused mechanics over the massive groups that just zerg the boss and the only thing different is "bigger health pools" with mechanics that can be largely ignored due to the sheer number of players participating. If you want massive 40 man raids then go play wildstar...but believe it or not, most people dislike those raid types. It's why WoW removed it and its why most new MMO's don't have it. It's just dumb.
