Game Mechanics RNGMETER for Lootruns(revised version)

Hello, I know this is a duplicate of my previous post on Lootrun RNGMETER, but I want to try multiple suggestions on how to implement this feature. This feature is for ALL players as a quality of life change!

Most of the time when people do lootruns, it usually takes two hours at most to get a full run of challenges before finding out you didn't get any mythics while having a 5,869 dry streak on you. However, I have different approaches on how to tackle this situation for all players trying to lootrun for a mythic.

There's of coarse the set Dry Streak, where this x amount of pulls will eventually reward a mythic. For example, we can use 5,000 pulls as the base model until somebody gets their mythic. Additionally, there could be an option for somebody to get a mythic they selected as their chosen item, but I'll leave this as a personal response along with the guaranteed mythic to be random type.
The next suggestion for eventually getting a mythic for somebody that is incredibly unlucky is to implement a feature similar to the forgery, where you'll get your mythic chances increased by a certain amount after reaching a milestone(in the forgery chest case it's to clear every single dungeon before you get the increased amount). Maybe every 50 challenges a person completes will increase their mythic chances by a certain amount.

Overall, people have different opinions on how mythics should be obtained. In fact, some people like the pure randomness regardless of how unlucky a person is. That's why I want people to vote for the best suggestion of how we implement this feature. By the way, you have unlimited selected responses if you find another suggestion appealing.
