Overwhelming Force and Avalanche

Do these KD proc enhancements stack? As in if I use both in one power will it KD more often? Thanks.

They stack, but not in a good way.  I'd be happy to go into details but in my experience choose only one for a given power.

Care to go into detail or link on why it's a bad idea? Thanks.

In CoH, knockBACK and knockDOWN are the same power, but it has different effects based on magnitude.  Anything over about 0.75 results in knockBACK, which scatters mobs and often annoys teammates!  Anything below about 0.75 results in knockDOWN, which takes the enemy out of action and leaves them in their initial spot.  Easy enough, right?

 

It is worthwhile noting here that the mechanism by which the Sudden Acceleration and the Overwhelming Force procs convert knockBACK to knockDOWN is that when the proc activates it checks the current level of KB, divides it by ten, then passes it on. This works great since generally knockBACK is almost always below 7.5, but things can get screwy when you add more things to the process.  
 

gotta hop for a few, but will finish this shortly.

Now when you start adding other procs that affect KB, it starts to get screwy, and that’s partly because I don’t remember exactly when effects are measured.  But let’s take your example and assume you have both of these procs in something like a damage aura.  If neither activates, nothing happens.  If one or the other activates, your enemy gets knocked down.  But if both activate then the KB is additive, over 0.75, and knocks the enemy BACK.  Although the KB to KD is supposed to eliminate that, it doesn’t to the best of my memory, presumably because of when the divide by ten thing happens and when it is just additive.  I tested a lot of this years ago but never wrote everything down so if I’m wrong or it’s changed let me know.

 

tldr stacking knockdown will often accidentally cause knockback

I did testing with a bunch of different procs, including things like the Stupefy proc.

 

Also, it’s worth noting that knockUP is a different mechanic, and you can absolutely stack knockUP and knockBACK on the same mob

Martial Combat - Ki Push often has some up angle to the target's flight path. As an added bonus the target does the hilarious windmilling animation.

As a side bonus, Martial is also awesome for other reasons.

Sometimes even in the same power, thanks Tornado.
