Yea, this reminds me of the elitist jackass who slammed me for using a Dreadnought in Cure elite because of its low turn rate and "One shot gimmick" phaser lance.
I "engineered" his demise as well. While he was making his little passes in his defiant on a pair of Negh`vars, I max offensive buffed myself and one shotted both of them with the lance (They were in single file, perfectly!). I don't think he realized they were dead because he got caught in the warp core blast of both ships at the same time and went "poof".
After his respawn, I just said "And THAT is why I use a Dreadnought!"
