Please consider option to exclude unlocked (not yet completed) contents from Roulette

[Rongway]

I'm a bit confused, how does not doing sidequest/optional content considered abuse?
If I didn't do any sidequest/optional content, shouldn't that "punish" me instead?
I'll have less content on my roulette pool, thus longer queue time for me.

The way things currently are, a player can unlock only the minimum required number of duties, never unlock anything else, and reap the daily roulette reward with a 50% probability of getting either duty in some roulettes. A player should not be able to by their own action or inaction affect the outcome of the roulette to a point of predictability or exclude content from the roulette when the primary purpose of the roulette is to increase participation in the duties that make up that roulette.

If the roulette required a player to unlock every duty in the roulette up to their current level and MSQ progress, they would have an incentive to unlock--not even a requirement to complete, just to unlock--more content, and then they would have much more content for their roulette to select from, and everyone who was, e.g., Lv60 would be able to roulette into any Lv50 or 60 dungeon, thereby increasing the roulette fills for people queuing for specific Lv50 or Lv60 dungeons, shortening queue times for people running optional dungeons.

Sticking with the Lv60 example, only 2 out of the 17 Lv50 dungeons and only 5 of the 13 Lv60 dungeons are required. Which means 77% of the Lv50/60 dungeons are not required to unlock the roulette; thus people who want to run those optional dungeons face increased queue times.

If instead the roulette required all the side dungeons up to the current point in MSQ to be unlocked, it wouldn't be a major burden for a player to unlock a few dungeons at a time as they become available, but it would be a major benefit to the roulette and people queueing for those dungeons directly because more people would have those dungeons unlocked. Further, requiring more unlocked duties in the roulette for everyone could justify an increase in the roulette reward, increasing roulette participation by another factor.

I would like to emphasize that I didn't mean the option to pick what duties to exclude from the roulette, just the option to exclude not yet completed duties.
I'm assuming if people unlock any optional duty, they plan to complete it.
If I didn't care about a certain optional duty/content, I wouldn't even touch the NPC.
(I personally haven't found any situation/reason where I'd unlock an optional content but don't want to complete it, if there's any that people actually do, please let me know)

I understand your intent. Your proposal could still be used to avoid duties in a roulette. Of course people intend to complete things they unlock, at the time that they unlock them. They don't necessarily continue to intend to complete every duty after experiencing the duty once. A bad experience in a duty, such as a vote abandon after multiple wipes to The Thunder God or certain raid floors--can change someone's mind about completing the duty tonight or this week. I have seen people decide to put off completion of a duty they had unlocked until some time in the future when a specific friend would be online because the duty was too hard for them without their friend.

In such an event, they should not be allowed to run their roulette with the incomplete duty excluded. They should avoid running the roulette or deal with the possibility that they might roulette into that duty.

In my opinion, putting not yet completed duties inside roulette pool doesn't really make sense.
If someone want to complete a duty that they've unlocked (but not yet completed), they'd queue that particular duty directly anyway.
And the roulette is there to incentivize people to "help" them.

And yet the roulette currently allows players to run a roulette with only two duties unlocked, with no incentive for players to unlock additional duties, and that doesn't help people running most of the duties in the roulette at all.

I assume you mean the roulette should require unlocking all duties, including optional ones.
So, only people who unlock everything can access the roulette? How is this any good for the game?
I understand if your point of view is "roulette is to incentivize people to login daily" etc., but roulette is also there to incentivize people to "help" others who want to complete their duty with matchmaking.
If you make it so that only those who unlocked all duties can use the roulette, you'll reduce the amount of people they can matchmake with, longer queue time for them, and for you too cause there'll be less people who can use said roulette.

No. See above.

people already abusing it by intentionally using low level gears and/or unequipping pieces of their gears?
And adding an option to exclude unlocked but not yet completed duty from roulette would not affect this.

Could you give another example based on the roulettes that we currently have?

If we implement the option, what kind of abuse potential, how and on which roulette do you think it will be abused?

Coercing a roulette result through gear is a separate example but it's still the same example. Even if the roulettes were fixed so that one could not force Labyrinth of the Ancients by removing gear, there are people who would unlock and attempt the Ivalice or YorHa raids, have a bad experience, nope out of them, and use the option you're proposing to avoid doing them in roulette.
