I think this is a pretty great and insightful response, but I would like to reiterate that a big problem with the entire farm is toxic gameplay behaviour that is neither particularly fun nor friendly to players. As Chimes wrote in the bluepost, doing this every single day with with 50 alts is mathematically correct, but not a great experience. The core of the issue is, and has always been, the experience of earning this is just not going well.
As you point out, the weakness comes from players making new characters, run the dungeon, and delete. It does technically give you “infinite” attempts per day, but adds a lot of work past attempt #50. Not a great solution to anyone by itself.
This would at the very least eliminate the need to have 50 alts, and that would be a great step in the right direction - that’s 49 fewer characters you need at the level requirement. It would still be a terribly boring and unending grind. It might even make players do more than 50 attempts per day, making it an even more unhealthy way of playing, because now it will be mathematically correct to skip out on sleep in order to get those 10 instances per hour capped. Slightly extreme example, I really hope no one would do that. The point is, now that there’s a limit of 50 attempts per day, they will still have time to do other things in the meantime.
The problems I’ve raised in the former point still stands, but at least you can do it on any character you want to play now.
This one, by itself, is a pretty tough thing to swallow - at least the exact way it is described. With this system, you will not only have to do the 50 runs per day, you will also need to farm as many tokens as humanly possible in order to maximise your chances. To make matters worse, you will need to do this on all 50 alts, because the most efficient means of earning tokens to purchase bonus rolls from would be to do daily quests on each of them. This is so much extra work for what is technically twice as many chances to get it. The bonus rolls would have to be rather trivial to earn if you want them to solve any of the issues.
This seems like the second point, but with extra steps.
See points 1-5.
Okay, so I might seem a little harsh here, I have highlighted the downside of each of the points because these ideas in many ways also have flaws - but by no means do I think it’s all bad and not worth considering. I think with some tweaks, much of these points can create a much healthier way to approach everything.
Edit: These criticisms are all assuming that you will still only be able to farm the mount during the 14 day Love is in the Air holiday period. If the mount was available year round, I think the discussion would have been very different.
I’ll have to criticise myself a little bit here, too, because only adding bad luck protection isn’t going to solve any problems either. It won’t make players not feel the need to maximise their chances, thus not making them play on 50 alts all day every day, the only change bad luck protection in of itself will change is the total amount of time they will need to put into the game (i.e. having an end post) - which might actually encourage them to put even more effort in, because the end of the journey seems much more tangible.
There’s no easy solution here, something will have to give. I hope the devs can figure out which approach is the best.
On the other system that’s been proposed, the “Yeti Essence” system: I think it would be interesting to test this system, but I also think a lot of players would get really upset if they tossed this in with a brand new mount, a brand new farm that might take 4,500 attempts to get. That sort of test would take years to conduct properly, the majority of players will not make even half of the attempts required even if they were given a year.
However, I think it is a fairly good system - it’s bad luck protection with a couple of extra steps, and extra rewards.
