In a recent discussion I was asked why I disdain the Spider Bot.
On normal/normal they get 78.4k DPS Raw. They move reasonably quickly and they also get a DPS boost. As a comparison, a cap of Laser Gatlings is 180k DPS Raw. I consider Laser Gatlings weak too, but that's more because of current armor mechanics.
They get a massive 6x bonus as well on swarmer, close combat, light, and ultra-light.
For Light (Fighter, Anti-Armor, and Bulletproof, Microfighter, and Spider)
MK I vs. Mk I Raw: Anti-Armor, dies in one hit, no need for boost. Bulletproof, it can't hit, it uses shell ammo. Fighter 2 hits to kill. Microfighter: 2 hits to kill. Spider: 1 hit to kill. This boost is un-necessary.
Ultra-Light:
4 Experimental Craft of Decoy, microparasite, speed booster, and translocator. Of those only one is AI usable (afaik) and that's Decoys by the support AI.
There's a few guardians that are ultra-light (Raider, self-destructor, sniper, and spider guardians).
For fleet ships: Parasites (3 hit raw), space plane (1 hit raw), Raider (1 hit raw, and can't catch it), Sniper (3 hits raw), and tele-raiders (1 hit raw).
Starships: Leech and Raid starships. It can't catch the raid starship but the boost to leech is nice. In general, though, another weak boost, even if it's a huge number. Mostly because it doesn't need the 6x.
Close Combat:
Acid Sprayer (2 hits), Autobomb (2 hits), Chameleon (3 hits), Cockroaches (1 hit), Cutlass (2 hits), Neinzul Swarmer (1 hit), Spire Blades (1 hit), Viral Shredders (2 hits), Wasps (non AI), and Youngling Nanoswarms (1 hit).
6x might be a bit silly here but it does mean they'll be better against much higher marks of ships. This is nice.
Swarmer:
Autocannon (1 hit), Deflector (1 hit), Laser Guardians (nice), Infiltrator (1 hit), Laser Gatling (1 hit), Commandos (2 hits).
There's nothing in this list that's even going to remotely take much to kill except for Laser Guardians.
Couple this with Low armor/hp (300 armor, 4.9mill hp cap) at mk I. Compare to cap of Gatling again which is 11 mill, or even Fighters which are equivalent armor, higher ROF and dmg/shot, cheap as dirt, and have a cap HP of (162k*98) roughly 16 million. Now, spiders are pretty cheap (400 material for a fighter, 240 crystal only for a spider) but they're speed bumps at best. One hit wonders.
Between that and them getting bonuses against almost everything they could kill in 1/2 shots anyway, it's kind of a pointless ship to me. If they could catch Raid Starships I might feel a little bit different about them, but that's a HUGE speed boost. If you're prepared for Raids, your regular fleet will chew through the one or two in a wave anyway.
