Personally I loved episode 30, I haven't read the manga but I think they got the point across in that one episode about how bad the Ishbal war was and how much it weighed down on people like Armstrong, Hawkeye, Roy and Hughes.
You could easily tell from the episode who loved war and who hated it, infact it was a slaughter not a war, even when they tried to end it with the leader handing himself over it continued, I thought the msg in this episode hit right where it was suppose too.
