Trial of Chaos: add dependency of dropped fragment on inserted fragments or selected mods on floors

(it's just a suggestion)

Hi, I'm playing in SSF league, completed 51 times Trial of Chaos, killed 12 times Trialmaster and this is the situation with fragments in my stash:
• left part: 7 pcs;
• center part: 8 pcs;
• right part: zero pc.

Again, I'm playing in SSF league and can't buy / sell fragments.
I realize that on longer range droprate should straighten out to 33% / 33% / 33%,
but at now I get left and center fragments 1.5+ times more often than right: 37% / 39% / 24%.

And then I wondered: why rely on smoothing out the droprate instead of giving players opportunity to influence type of fragments they drop?
After reading a ton of posts on reddit and endless talking to my mates about loot, I came up with two possible options to help players in solo leagues get the fragment they need without breaking economy on non-solo leagues:

1. (variant for casuals) Obtaining only those fragments from 10th floor bosses that are NOT inserted into the Trialmaster seal.

Example: if after completing 10th floor I go to the Trialmaster seal and insert left and center fragment, then from all subsequent bosses of 10th floor I will get right-side fragment (because only it is not inserted in the seal) until inserted fragments changes.


2. (more interesting variant) selectable Modifier of each floor increases by +10% the chance to get a fragment with corresponding positioning: left / center / right

Example: on each floor I choose one of three modifiers; when going through ten floors I chose "left side modifier" twice, "center modifier" three times and "right side modifier" five times.
When killing the 10th floor boss, fragment droprate will be as follows:
• left part: 20% chance;
• center part: 30%;
• right part: 50%.
