personally i've found swapping gear to kill the EP often results in it dropping nothing.
another point of some interest is the longer you take to kill an EP, the more it seems to drop. use a big powershot on it and it dies one hit? will often drop nothing.
use subpar equipment and take 20+ hits? generally more, doesnt mean it won't just drop nothing, that still happens.
This is more obvious on well mobs. Also SQN is correct on how ML is useful when item is thrown in then sidedrops are based on ML when mob dies.
I've not done the maths on it as i'm personally not that interested and just doing by what i think works. I doubt it will be proved/disproved unless someone can be bothered to do a lot of testing similar to what i did for critical hits.
Similarly i have a much different idea to how much QD is valued and i think the entire community is mad for not prioritising it more.
From a logical standpoint, if you had 100% quickdraw you attack 4 times as quickly, if you have 100% crit you do twice as much damage every hit. Which one sounds better to you? Main drawback of quickdraw is that it's not usable by casters. The secondary drawback is often the second hit is wasted if you're not on the ball. if the mob dies and quickdraw procs then you need to click onto the next mobs quickly to make the most out of it. Saying that, this is why i don't think crit is that special, no real point killing a mob with 100 hp left with a 2400 damage crit, much better to quickdraw and get a second hit on another mob.
Heavy weapons in particular are much more easy to use the extra attacks given the extra long delay between hits.
Oh my gosh... there are so many things that contradict other things you posted base on MY PERSONAL experience playing the game.
#1... you and many others have stated it openly... it is the RNG GOD factor.
Here is something I do often over the years... I am level 50+ and throw in a Tier III / IV or V item into a Well (because I have those only left while the well is still active)... and guess what... I can get 8+ SIDE DROPS when I one(1) HIT kill it off, and even when I use an ability like RETRIBUTION.
It is RNG GOD factor... and yup, I have done this at level 73 even.
Also... one(1) hit killing an Evil Presence using Retribution with a Heavy Weapon can result in 1 item drop, 12 item drop(s) and either all crap or something good.... RNG GOD factor.
The speed in killing is NOT a factor ... so you can one(1) hit kill and get a great drop or crap drop, the same goes for 10+ attacks ... the RNG GOD factor.
Hey... YOU and others have mentioned this for over a decade, YOU and many others HAVE STATED THIS FACT TO ME IN MY POSTS BEFORE... so... why are you contradicting yourself???
