Why do people do Dynamis? For the challenge, I suppose, but those in it for the challenge are probably going to quit long before they ever get past the 4 main cities.
Dynamis for Relic armor? Very job-dependent. For the 2 jobs I could either do Dynamis with or are leveling to 75 (MNK and SMN) there's really one one slot on MNK I'd want. SMN has a lot of very day and weather specific pieces that might be nice here and there but with Yingyang Robe as something I can get instead that drops the ones I'd want to maybe 2. And for others who'd want pieces, they're likely gone once they win the lot.
Dynamis for profit? Nowadays it's kinda viable. I have no idea how much currency drops in a random Dynamis but I'd assume at least 100 in total. 100*40k = 3 million profit, not to mention synth item drops. But 3 million profit split 40 ways is still only 75k a person. Obviously if you get a lucky run and a few 100 coins drop or something you're going to make a lot more (and you'd know a lot more than me exactly how much currency you get in a single run. However, your 600 million gil/7 months figure would assume you're getting nearly 11 million in profit per run. Does this happen often?) but even at 200k a run most level 75 players have multiple ways to make at least this much for 3-4 hours of their time that won't require them to lose XP. Hell, I can imagine particularly barren runs where the gil/person doesn't cover some people's consumables. For someone like me (and like a lot of other people) if all you can offer me is X amount of gil for my time and effort, why should I say yes when I can make more than what you're asking for much less risk?
Then, finally, you have people who Dynamis to get one person a fully upgraded Relic. The ultimate penis wave, really. And for a lot of hardcore, dedicated players, giving up that 'me first' attitude and seeing one of their own come out with the best this game has to offer gives them warm fuzzies. Am I one of those people? Not really, but then again I'm not one to judge who 'deserves' something like that over anyone else. If someone came up to me and said "Hey, Cubs, if you sponsor all our Dynamis runs we'll get you either a Spharai or a Claustrum!" I'd probably say yes simply because they'd think I was worthy to wield it. I'd never outright tell someone I want something like that, because having a Relic weapon isn't one of my in-game goals.
Yet, anyway.
We see that dedication on other servers. It's why BG has a relic. It's why so many JP shells get one member a relic. I actually think you're going about it the right way, Peregrine, in the sense that I don't think this server has 50 people or so willing to set aside their goals and their wants to be a part of helping a single person rise to the top of the mountain. Everyone's either too proud, too jealous, or too lazy to want that goal. At this point, anyway, I don't think banding together to get one person a Relic is at all a bad thing. Our server doesn't have any NAs with one and, quite frankly, we're behind most every other server when it comes to just getting the shit done that seems commonplace on other servers.
But at least we have a decent economy. Not really the point though.
Would I be a part of someone getting their full Relic? Maybe. I've never had the Dynamis bug bite me, so I couldn't tell you if I'd enjoy it the first time - much less the next 50+ I'd need to do to help them.
Would I be happy if others wanted me to get said full Relic? Absolutely. I'd be honored, overjoyed, want-to-fly-to-your-house-and-hug-you-IRL that a bunch of folks would say "Hey, he should have full Relic." It's a pipe dream, though. I don't think I deserve one simply because I'm not yet satisfied with what I've done in-game. I have a lot more to do, and more importantly, I want to still have fun. I don't want to agonize about how many 1 coins dropped. I don't want to send furious /tells to people who just couldn't make it to the scheduled run.
I think Quetzalcoatl, as a whole, needs to be put on the map as far as other servers go. Kaizen is a good first step. Getting someone, anyone a full relic would be another. Shit, maybe we'll be the first server to beat Absolute Virtue.
I doubt it, but wouldn't that be great? I think I'm ready to take that step away from myself and towards making this server a more respected place.
Sadly, I don't know if anyone's willing or able to follow in step.
