Should I replace Hecatomb proc with Force Feedback proc?

I've got an Inv/SS tank with a full Hecatomb set in KO Blow.

It's easy enough to quantify the Hecatomb proc:

Per Mids, the Hecatomb proc has a 33% chance of adding 107 pts of Negative Energy damage. Which averages out to (107 divided by 3 = ) about 35.67 pts per use of KOB. So, over the course of a minute it would add:

60 / 7.64 (recharge time of KOB) = 7.85 x 35.67 = approx 280 pts of extra damage over the course of a minute.

As I said, the Hecatomb proc is easy to quantify; the FF proc, not so much.

The FF proc has a 10% chance of firing per use. When it fires, it provides a 100% increase in global recharge for only 5 secs.

Now, my current recharge time on KOB is 7.64 secs, which comes from:

Rech-KOB = 25 (KOB's base recharge) divided by (1 + 1.375 [my global recharge] + .8993[recharge from Hecatomb]) = 25 / 3.273 = 7.64 secs.

Damage done over the course of a minute = 60 / 7.64 = 7.85 * 330 (KOB's damage with Hecatomb with no proc) = 2591 pts of damage.

Now if the FF proc has a 10% chance of providing a 100% recharge boost, i guess that averages out to a 10% recharge boost overall. Which would change the 3.273 in the above equation to a 3.373, which would lower KOB's recharge time to 7.41 secs. Which should change the damage over the course of a minute to: 60 / 7.41 = 8.097 * 330 = 2672 pts of damage.

That's only about 80 pts of damage more than Hecatomb with no proc. Of course, that's only 80 pts of damage from KOB; but since the FF proc is a global recharge buff, it would affect all my attacks. But if I'm only getting an extra 80 pts out of KOB, I find it hard to believe that Jab, Footstomp and the others would get much more. I doubt they would come close to the 280 extra points of damage per minute that the Hecatomb proc would generate.

Teal Deer: what do you all think?

1)Get rid of the Hecatomb: Damage (the single enhancement); keep the proc.
2)Add an Unbreakable Restraint: Chance for Smashing damage to the now open slot in KoB.
3)Put the Forcefeedback proc in Foot Stomp.
4)???
5)Profit.

I wanna just chime in here and say that putting the force feedback proc in any single target power is a waste. The proc will roll a chance to fire for each enemy it hits (it won't stack, though). So put it in foot stomp, or nowhere.

Also, I totally blanked on this, but your hecatomb set should be in Haymaker, not KoB anyways. I guess that's my #4 on my previous list. >_>

D'oh! I forgot that the FF Proc could go into Foot Stomp! Thanks for the replies.
