I saw this once when long dead and watching the spectator cam, and like a trainwreck, I just couldn't look away. It was an Oxide, pre rescale mind you, with two LRM5, a NARC, and moved less than 110 kph. It was predictably horrible, but...of all the bad mechs I've seen, I've never and never since seen a mech quite so horrible. I think it looked something like this.
I think what makes this build really bad for me though was that is was a carefully calculated build. It's bad, I think that's obvious, but the person knows enough to realize NARCs drastically improve his LRMs, and knows that you can squeeze in more ammo with weight manipulation (in this case...the bad decision to put in a smaller engine and a heat sink for one more ton of ammo). More to the point...two LRM5s? It's a 10 point alpha with none of the DPS associated with low alpha mechs, with one of the most easily countered weapons in the game. I just have no words for this. Someone spent real money to make that.
