At first, I was going to go with this Vagabond. You would think that someone living in 0.0 would take the time to Google "Vagabond fit" and at least learn the basics of how to fit this ship. Hell, there are whole articles on how to fit a Vagabond properly. Plus some guy named Jester talked about Vagas, too.
In the face of all of these easily-accessible facts, it's hard to understand how someone could gather together this much fail and place it on my beloved Vaga hull. It's a disgrace. Happily, this ship is dead, it deserves to be dead, and hopefully, this guy's corp-mates will explain to him why.
So yeah, that was going to be the kill of the week. But EN24 picked up a really terrific article about a kill that is much less fail:
Here's the related EN24 article. It includes a great BR on exactly how this kill happened, and it's something I recommend anyone interested in EVE PvP read. It does a fantastic job of explaining how a small, quick ship can take on a much larger, more expensive one and still win. The Sentinel used to be one of my favorite PvP ships, but in the age of sniper HACs, EAFs became much too fragile. Happily, this pilot found a target that one can still take on. And HACs have fallen out of favor... hmmm...
Anyway, it's a great kill on the part of the Sentinel pilot, but some of the responsibility has to rest on the Mach pilot's head as well. That's not the best Mach PvP fit I've ever seen... not even close. Even if you accept the fit as posted, what a solo PvP Mach was doing without Depleted Uranium ammo in cargo and at least one flight of Hornet EC-300 drones, I can't even imagine. (Note to self, for at least the third time: write and post Projectile Ammo Guide.)
Still, that's how EVE is. You pays your money and you takes your chances. Sometimes, you die hysterically. And other times, taking a chance results in an epic 1.2 billion ISK kill with a frigate. As the SAS puts it, "Who dares, wins".
