You guys sure ambush works w/ grenades? The description said ranged weapon and off hand I don't remember nade criting with "Ambush!" sign in my game plays.
It doesn't; the point is that you can use an incendiary grenade to illuminate targets for Ambush, so anyone can make use of the feat, not just people with incendiary pistols.
your point about incendiary grenades is addressed.
Denying the validity of using utilities to set up ambush situations is somewhat absurd, I think you're just withdrawing into a strict weapon vs weapon position to try to make your argument more tenable. Lots of builds use Ambush without access to an item that goes in a weapon slot and can set things on fire, that doesn't make use of Ambush an invalid consideration in the effectiveness of those builds. The question is, which weapon makes better use of Ambush, a chemical pistol or a firearm? You can illuminate multiple targets at once with a utility rather than wasting shots doing it one at a time with an incendiary pistol, and the .44 can deliver much more devastating criticals than any chemical pistol.
the original statement that I replied to said the maximum damage, so my point still stands that the original statement is incorrect counting the on hit effect of chemical pistol.
You should reread that statement. It says that with a chemical pistol you're trading 3-4 times the maximum damage for damage over time. It also says that even with damage over time accounted for, the weapon can't match the average damage that a .44 would have dealt immediately. I'll concede that I was specifically talking about acid blob pistols in that case and didn't specify. Since you're still insisting that acid blob pistols are worthwhile, here's a bit more number crunching, all components QL130:
Here's the acid blob pistol itself, since its on hit effects don't show up in combat stats:
We'll just look at standard shots, no criticals/specials - those would skew the figures way out in favour of the .44. The .44 averages 143 damage per shot. The acid blob pistol averages 63 damage per shot. If the acid blob pistol's on hit effect occurs, and if it is allowed to deliver all of its delayed damage over the subsequent 2 rounds, its average goes up to around 208 damage per shot. Its on hit effect occurs 46% of the time. 46% of 208 plus 54% of 63 equals around 130 damage per shot on average.
In other words if you are willing to juggle enemies to avoid wasted damage from lack of proper effect stacking, and willing to let them die over a period of three rounds rather than immediately, you can squeeze almost as much as the average damage of a .44 out of an acid blob pistol with a standard shot.
So what do you actually get for using the thing? Well, you get acid entanglement, and you get acid damage. You seem to value the latter very highly; I don't, I've found the ability to switch between JHP and W2C rounds much more valuable than the ability to switch between damage types, because I would rather be able to mitigate (or punish a lack of) resistances to my primary weapons's damage type than have to switch to another weapon depending on the target's resistances. The choice ultimately comes down to single-target CC, or higher damage/stronger criticals/stronger special attacks. I can't possibly see a case for the acid blob pistol in those terms, as its on hit chance is always too low; even with a QL150 dispenser it's a coin flip, which is simply not good enough for a single target weapon that is so weak in every other area.
very useful effects like entangle and fear that make some fights trivial compared to 0.44, one fight that I can think of is the carnifex fight.
You don't say?
