Sadly, it's working as intended.
To every scissor, there shall be a rock admist the paper to keep you on your toes and provide a significant increase in challenge.
I feel you, though, mang. :/ It's just something that's horribly unlikely to change.
Hmmm... well my main is a PB so I'm quite familiar with KB 
for Soloing, your idea is good, but teams tend to hate KB of any kind, and your idea will actually make it likely for more Spawns to get KBd than currently do - that's sure to increase our popularity with the Tankers haha
So, unless they make KB more beneficial and welcome (perhaps increase damage if KBd into walls, etc), then I don't want a mechanic that will upset my teammates even more than the grief I already bring

Perhaps there could be a new mechanic devised for EB/AV encounter where so much KB would equal a Stun or Disorient type effect or something.
For blasters, maybe build-up can be used to raise the magnitude of kb high enough to affect EB/AV. I think it would be thematically ok, and it wouldn't be unbalanced as the effect only comes into play when build-up is available.
I think the big issue with KB against EBs and AVs is the small amount of time you can affect them with it. PToD should either not affect Knockback, or it should have KB on a different timer so that you can knock them down more often.

I think you underestimate our fools, sir.
Why /duel is a bad idea
Now before I get burned to a crisp I would appreciate the time to explain my intentions on posting this Suggestion.
I would like Knockback/Knockdown to be more effective on tougher foes. I'm not entirely sure how to go about addressing the dilemma but this is why I posted the thread; to get some feedback.
Most recently, I have been playing my Energy/Energy Blaster that is tons of fun to play (currently levl 47). Knockback is very fun to watch and gives me that superhero feel when I launch a critter 20 yards.
However, I seem to have trouble with tougher enemies like EBs and some Bosses. The only secondary effect my Blasts, and some secondary attacks, offer is KB/KD which can be nullified by some Bosses and most EBs/AVs, if not all of them. I find this troublesome.
I will decimate mobs and critters throughout a mission, having great fun only to hit a brick wall once I find out there is an EB at the end of the mission. I end up winning but not without the help of many many inspirations (mostly lucks, etc) and 1-2 hospital trips (stupid Anti-matter) which can take away from some of the fun.
So my suggestion is to create a new mechanic, or revise the current one, that allows my KB to stack on EBs/AVs (maybe bosses) long enough for my secondary to be of use on tough opponents; whether that's KB/KD or just a moment of breathing room, I don't care.
