Your numbers for H2H trial are low and are false in the eyes of your opposition (H2H) as to Ochain. While you aren't arguing with anyone in particular, you are arguing with a thing and that is your subject.

Saying it would take 250 days isn't itself false either, but to even present that as a logical option infers you are playing up your argument for the sake umph factor.

While doing this, again, you are disregarding that H2H actually takes a large amount of "time" to complete and its own range can vary as drastically (though not quite as drastically as the made up spectrum of 250days) to complete.

It's not the most solid definition of straw man, but as I read it it fits. In either case, the only realistic part of your post was that SE ignores external variables, though your reasoning is off. I can't say why they do what they do because in the end it doesn't "fly" for most people and is only enhanced by the fact that this game doesn't have a lot of life left, especially with what we're being offered.

Other examples would be Relics (Dyna revamp) or Mythics. The inordinate amount of time it has taken to complete these throughout the ages demands a lack of interest for the other parties that would have to be involved in creating said items. There should be difficulty as there SHOULD be difficulty for Brochain/Dardaubla as well.

In the case of the latter, the options you have are difficult mobs vs. time to complete vs. limiting spawns (again controlling time, but this factor is enhanced by the # of people desiring said items but can also make the trials really easy). In abyssea, they aren't left with many options from that list.

Lastly, there is only one "difficult" stage of Brochain/Dardaubla and that is the one in question, they have addressed two issues a) increasing change rates and b) Maere/Brulo drop rates being broken still

When these are fixed and it's still bad, then you guys will have a new argument. As it stands they can only fix what they fix when they fix it. (And I largely find SE to be incompetent with regards to what the game needs, but in this case they've at least addressed some of the bigger issues)
