I watched the first 2 episodes when it came out, wasnt that into it :/ Soul Eater would probably be good in whatever language >.> also in the sub Maka's voice didnt seem....
Because it's several Titans, Armored, Colossal, Smiling and so on, so it becomes in plural. I know it's Attack on Titan, but it's something that automatically just happens.
I've seen the anime twice and caught up with the manga, I have never felt the urge to say Titans xD I either refer to it as Attack on Titan, or Shingeki no Kyojin, but I see your point =P
I don't get dubbed, its so.... americanised..? is that the word? anyway, I feel like it loses something and changes.
