So I have been doing some testing.
Some things people might be interested in.
General Ability vs Porc:
Raiders and Assaults are not very different vs light porc. The best of them generally require about 2x value in the attacking units to make the strike efficient, while even the worst setup needs 3x value to begin appreciably damaging the porc (Blitz, as it turns out).
For Raiders the Ranking is:
Glaive
Bandit
Duck
Dagger
Scorcher
Pyro
Blitz
Kodachi
Flea (never actually makes cost vs a LLT, even if you have way too many of them, it just kills too many first)
Puppy (like Flea, but worse at this).
This is for how easy it is to make cost against LLT really. It ranges from just under 2x for Glaives to 6x for Kodachi and Blitz, so its quite a range.
If I were to Rank all Raiders and Assaults on usefulness for raiding and killing light porc, it is as follows.
Scorcher
Jack
Halberd
Glaive
Minotaur
Ravager
Knight
Bandit
Thug (A bit hard to place because of the support effects of its shield).
With all others being approximately the same, and a distinct step lower than the rest. They all have faults that stop them from being effective raiders. Duck, for example, drops out massively because of its lack of sustained ability to damage infrastructure.
This is of course just for raiding potential, it doesn't even count fighting a raider defense force, nor the effects of terrain.
The top 3 of this list, all have some distinct weaknesses (especially Jack if I am to be believed).
Now, one might as 'why have I posted this' and that is fair. I suppose I mostly wanted to record the results of my initial testing (on raiders and assaults vs llts) and some extrapolation I made for general consumption. I found the implications to be interesting, for example how Scorcher isn't actually that good vs LLTs, but is big enough and has enough DPS that it can probably wreck infrastructure meaningfully anyway.
