Well...yes? It's not like we've had a Battle of Blackwater this season.
What like when two direwolves ripped people apart earlier in the episode?
you have apparently not the smallest understanding of how this works.
they have elaborated in interviews how they had to fight a lot with HBO for the blackwater battle and convince them that its really important for the plot and the show wouldnt work withhout it, and then they got a limited budget for it.
and even with that, apart from the explosion, we didnt really get an epic battle we know from hollywood movies, everything felt small.
they simply didnt get the money for that direwolf scene, I am sure they would have loved to have it, because after all, who wouldnt? but its not important enough and they know that certainly nothing is "completely ruined" now, thats why its not in the show.
