Path of Exile is not such a gamble
I'm pretty sure with enough research a semi-accurate spreadsheet for chancing uniques can be made. There has to be people around who recorded their experiences chasing such uniques. I know i saw some of them. It is a huge difference wheter a certain unique can be chanced within a couple hundred path of exile orbs, or several thousand or even beyond that. Without having any idea or giving any statistical information, entirety of the video can be explained via explaining how chance orb works. Making an item list imo is redundant.
Would still be better than nothing. Besides i'm pretty sure items such as headhunter would be amongst the top in terms of sample size. If you were chancing such an item its highly likely that you would've count the poe orbs you've spent.
Yes it is very likely amongst the top chanced items that is "counted". Would not be hard to get info from at least a dozen attempts and yes that would be as i've said earlier "semi-accurate" which is better than nothing and not at all misleading if you know what you are getting.
Not misleading one bit if you tell the people how many accounts you have counted. A newbie might see this video and think, "Hey a HH is worth over a hundred exalts maybe i should spam chances on leather belts while using zana.I can afford it if i gather my own leather belts." Same guy would most likely not attempt it if he knew he'll spend more than 10k chances on average for such an item. You dont need exact ratio to paint a picture in your head. So long as you know how many Path of Exile orbs were spent, items chanced you'll have an idea which is the point. You make the judgement.
You dont play poker do you? Same principle, its not such a gamble if you remove as much unknown as possible. Thats how pro's play, by calculating their hand therefore having an idea how likely they are to win and proceed accordingly, and these guys play for real money. It doesnt always work, therein lies the gamble but in the long run you'll have the dice on your side. You may not care to this end as i gather you want to truly gamble then do so, but do not presume that is the norm.
To be honest anyone who has been playing the game for a couple months would know which items are valuable. Even if you didnt know somehow, it'll happen the second you discover Path of Exile. Trade for gods sake. So tell me what did i really learn from this video? What did it add to my game knowledge? I like lifting's usual videos, as they give me ideas about different builds, but this one i found pointless to any level of player.
Also if i cared enough about it i would compile the data, but definately not gonna do it because a stranger said so, its silly to even suggest.

Uniques are not all of the same rarity
if a unique tier is chosen for which no unique of that base exists, then the item defaults down to a rare.

A lot of people will try to defend Path of Exile as not beeing P2W
As for me, I feel Grinding Gear Games is one of the few companies out there who deserve the extra money they get with their free to play model. They do a really good job of providing updates and new content on a regular basis

Same with giving Path of Exile bosses a resolve bar
A voidheart jugg will lose some damage but not really care that hydra is poison immune, a Path of Exile chaos barrage or spectral throw will be able to kill hydra but will have to actually play the game
