Right, so... Tonight I'm pissed off enough to actually waste some time demolishing your reasoning step by step. Let's start it.
Except it's already doing 3552 on impact (2). In order for it to do no more, you would have to kill the target literally instantly after the first incinerate. Let's compare DPS:
A claymore build, with maximum possible weapon damage, will do about 2500 DPS (3) from the claymore+ammo, 600 DPS from cryo blast+incinerate+explosion(once every 7 seconds, on armor) (4), and *maybe* 200 damage from the shock turret, every 3 seconds. A grand total of around 3160 DPS.
A Talon build, with maximum power damage and pistol damage, will do about 2000 DPS from the talon+ammo (5), plus 3 casts of incinerate (6) (plus 1 cryo) every 8s for 1600 armor DPS, + 3 explosions for ~400 DPS (7), + ~650 DPS from the turret (8). A grand total of 4650 DPS, Nearly 50% more DPS than the claymore build.

1), which you're not gonna find above, unlike the rest: loldps. No seriously, thinking of dps as the end-all of all statistics about the effectiveness of a gun, power, kit, build or loadout or whatever is just... Stupid. And I'm not gonna delve more into this if you don't realize it yourself. By the time this post is finished, I'll already have wasted more than enough time on it. I suppose you could try and read what QMR wrote above, maybe it might help a bit.
2) Except that it doesn't. 25% of its base, non-dot damage comes as a dot too, which means you're gonna do exactly half of that 5.3k figure on impact, which means no more than 2.7k. Certainly not 3.5.
3) Wat. What kind of enemy are we talking about, firstly? Are we talking armor, I guess? And an enemy with a 1.4 headshot multiplier, I guess, since that's what turns more in your favor. If you start comparing things with 2.5 headshots as a factor, well... Lolpowerdamage is all I'm going to say. So, 1.4 headshot bonus.
Even then, your math is wrong. This build has a claymore + ammo dps, on armor, of roughly 3100, and that's without taking in consideration the incendiary glitch, which is actually gonna skyrocket it probably more around 4k. But let's compute things assuming everything was fair and square (even though it isn't). 3100, not 2500.
4) Now would be a good time to understand why your build acts for 8.59 secs (see below) and mine acts for 7. So I'm gonna go ahead and suppose that I'm gonna get a second incinerate in, but only taking into account the dps of it for roughly the second and a half I've got left after the 7 have passed, which I think it's fair. It turns the 600 dps into 700.
5) Now, let's compute this again, shall we? Since you didn't provide a build yourself, I made one for you, which I believe is the best you can do with a talon and the power amp and incendiary for the explosions. It ends up to 1900 dps. I'm not sure if you just approximated to 2k, but if you did, then yeah, convenient, uh?
6) This would be the moment when I point out that you actually need 8.59 secs, not 8. Careful with the approximations. As I said, I already kept count of this in the other incinerate's dps calculation.
7) Lolwut. You can only detonate one explosion from incendiary ammo, unless you stop firing for 4 whole seconds which you're obviously not gonna do. 135 DPS.
8) LOL! And why is it, exactly, that your turret does 650 DPS while mine does 60? Space magic? Or you think it actually fires once every cooldown? Or are you just ****** kidding me, really? Dammit, you must think I'm an idiot. Bad for you: I'm not. If my turret does 200 damage every 3 secs, yours does around 300. That is, 100 DPS.
9) So let's compute the results, shall we?
Claymore: 3100 + 700 + 60 = 3860.
Talon: 1900 + 1600 + 135 + 100 = 3735.
I'm not sure if you intended on skewing the results towards your build (in which case you're an idiot if you think I would fall for it), or if you just couldn't do the proper math yourself (in which case you should probably avoid making such posts).
As you can see, the claymore's build's numbers, that almighty dps you're so concerned about, is higher than your build.
But not just that.
It is higher in the only situation in which your build is actually somewhat competitive with it.
That is, an opponent with armor *and* 1.4 headshot multiplier *and* no damage spikes *and* no multi-hit glitch *and* no power blocking auras.
Do you know how many such enemies exist in this game?
I'll tell you: one.
Just. One. Single. Enemy. The bloody goddamned Geth Prime. (which you should rocket on sight, by the way, so it shouldn't be counted).
Against *any* other enemy in the game, one or more of the above conditions fails, which results in the Claymore build's DPS taking a much bigger lead.
Not to mention that you're basically useless against anything which still has shields or barriers, since your incinerate DPS gets cut by 66% (lol!), and not even the 1.5 multiplier of your (broken) gun can make up for that.
Not to mention that I also didn't account for the incendiary ammo glitch, which is going to do *a lot* more benefit to the Claymore build than to the Talon one, probably making up for another 200 or so DPS difference even in your ideal circumstances.
Not to mention that, even if we assume that we really care about dps (lol), we're still only talking about sustained DPS, which is pretty much bullshit, as burst DPS is a much more important factor in this game. And you do*not* want to compare burst DPS of those two setups, trust me.
And last, but not the least. Again. DPS is a stupid number that doesn't have even half the meaning you think it has. There are so many factors that are not represented by it such as range, accuracy, speed of your kit (I got an adrenaline module, you do not), OHK capabilities, etc. TTK would be a much better representation of the usefuleness of a kit/loadout against each enemy. But even then, there are flaws with it.
The only thing that doesn't lie is experience. You get down in the battlefield, you try things out, you learn which one if the best. Theorycrafting will never be as truthful as that.
You clearly have never seen anyone play a FQE with a claymore the right way. I'm sure the first time that'll happen, you'll realize how wrong you are.
