Played three times against my wife and friends and won with various lists that had Defenders in it from traditional 100 point game to 150 point games. Each game the Defender was a workhorse with the white K-turns and added survivability helping to win every game.
So while I realize this was a small sample it did make me question why so many X-wing players are so down on the Defender. I play at my local store and most of the players there had a very low opinion of it so I know this is not just some random message board agenda. In my experience it is a great ship and while I admit a personal bias to it being my favorite ship to play in any version of the X-wing/TIE Fighter PC games from my younger years it seems to be a good ship in this game.
I realize you fly casual and play the ships you like but I'm really confused as to why the Defender has the rep it has.
