Seraphs are armed with two Energy Flingers around their ugly face and a bunch of bombs. The Covenant have no technology to make missiles so the Seraph has to desperately try to drop bombs on other starfighters. This explains the Seraph kill ratio- 1 kill:5,000 deaths. The Energy Flingers are so pathetic its like the Covenant are using fighters from WW1. There is just no point in using them. To try and even the odds, Seraphs were soon equipped with shields. These completely changed the Seraph kill ratio to 2 kills:4,999 deaths. That could be considered an 'improvement'.
