Low Buged range or hidden feature?

Description of the bug: (optional screenshot/video): The range on basket displays on my DK like this:

So my minmum damage being 4919 the least I can do with Crusher + Zerk should be 4919x170%x2= 16724
But after a lot of hits and rolls I have seen that the least damage I can do is 26.7k or so (Max damage is accurate knowing that I may lose a bit of damage due to defense).
I have asked other friends and seems that is inaccurate on me only as a DK so I have been thinking that either the range display is wrong on DK all together or is Beholder extra mastery that isn't showing up on the range.
What is supposed to happen?: Display the correct range
Where did you find and/or notice this bug?: Checking my damage and my range

Extra information (optional):

 

I am not sure, this bug or what ever it is, is always there my minimum range is always very low no matter if I use a por or not. I know how the stabing swing works but I asked the range to a paladín friend and he had a good range in terms of making sense and as far as I know bw also have different damages depending on animations. Thats why Im asking if is beholder extra mastery not disolaying or maybe is something else

 

W8 I thinked about it and you may be rigth, after some calculations that very low range fits with the swing animations, also I just rmb paladins blast has a random animation like power strike so I would have to as a hero or a sword paladín. But what you said makes sense, thanks!

 

The HB is not happening to me, just when Im full hp aura of the beholder heals me from 30k to my max hp without hb. Im not sure how all is coded o.o

 

All makes sense to me if I make numbers. Spear stab has a multiplier of 5 and a swing of 3 (the oposite for Polearm) What I was missing is the fact that the range take into account both ranges making the range bigger than it actually is if you foce animatios with skills. Now what im not sure if beholders mastery is aditive (60+20) or multiplicative what im sure my minimum damage is 72% or so my max damage (I didnt calculated the mastery on the formula but I may as well do) Noting is broken so this is not a bug as far as I know. the hex of the beholder bug and somehow eiji losing hb cos of hex is weird tho

 

I just did numbers, Beholder mastery works and is additive 60+20= 80% mastery is not just that the minimum damage times the mastery, it has a place on the range formula. So we need to put this as not a bug and adress in another post the HB issue and the aura too. All this seems weird from my perspective since I also have maxed all the beholder stuff and get different resuls
