It's been a long time coming, but I finally have my Teladi Buzzard Vanguard:
It's almost completely decked out, the only thing missing is that the center hardpoint, right below the ****pit, is currently empty; it will eventually house a mk2 tracking missile launcher. Top of the line engines, top of the line thrusters, top of the line shields, top of the line software, and 2 mk2 shard batteries (basically shotguns). Until I get my missile launcher (soon), I won't have much return firepower at range (in theory shard batteries have a maximum range of nearly 3 km, but in practice they're not very effective past 800m or so), but if I close distance on a target, the shard batteries will shred enemies rapidly.
I can go toe to toe with any other heavy fighter, I obliterate light fighters, and scouts... well, they're a problem because they're so damn fast and maneuverable, but at the same time, they present no threat to me, because they simply don't have the firepower to get through my shields unless I do something really stupid. All I need is one dumb mistake from a scout and my shard batteries will vaporize them. As for larger vessels, I can definitely take on freighters, not that I turn to piracy, generally, but gunboats and frigates would be a big issue, since they have so much more firepower than I do, and I don't have the correct loadout to deal with them (if I ever do decide to try to take on a gunboat or frigate, I would swap the shard batteries for plasma cannons, and swap my eventual tracking missile launcher for a torpedo launcher). Still, I would at least not get instantly vaporized by a gunboat, so I at least would have the opportunity to flee. (The Buzzard's biggest drawback is that it is relatively slow for a heavy fighter and a gunboat or frigate could mostly keep up with me, but I could certainly outmaneuver them, my turn speeds are way faster).
