If converted to "Arch Dynamis Lord Kills" the following would happen:
Teamwork, you'd have groups of people banding together to do this fight, and everyone involved benefits.
Umbral Marrow, since it's still needed for the ridiculous second trial, it's actually make it available for people to try. When you have hundreds of teams killing Arch Dynamis Lords, eventually "A Select Few" will be able to attain the supply needed to finish that trial.
Also needing recognition:
Time Limits, It hasnt' been brought up at all, I'm amazed. You can only be in Dynamis for two hours, once a day.
The pre-pop NMs needed to pop Arch Dynamis Lord need a considerable amount of man power and time to kill too.
In short these trials will NEVER be done "In a Week".
And the big thing that seems to be forgotten:
Some of use spent in upwards of Two years doing Dynamis:
>> Throwing money into the void, upwards of two years of Hourglasses at 1,000,000 Gil a pop.
>> Gathering 32-64 people together for the benefit of one person, and all the problems that come with that.
>> Trading ancient currencies.
>> The waits needed between trials.
>> Finding crafters for the requested weapons.
>> Setting up "lost runs" that were dedicated to killing attestation monsters, repeatedly because the drop wasn't guaranteed.
>> Setting up "lost runs" to farm the fragment NMs only to have them warp out on you. and having to set up another run to retry.
Then:
Subsequent trials where you need to Killshot countless monsters. Yes you lowered them. But some of us actually did it "The hard way" upwards of 9,000 monsters, +/- misses.
Then:
Kill your attestation monster 5 times.
Not so bad now cause you can pop multiples, but when I did it, that meant another 5 hourglasses at 500,000 Gil ea.
Then:
Kill your Fragment NM 10 times, which was reasonable.
20 Ubral Marrows seems a bit high to me. But 20 Arch Dynamis Lord kills seems Decent to Good. It benefits everyone helping and could be fun in the end.
