We need a way to conveniently exchange Poetics!

[TheRealMadruck]

Allow an option to trade Allagan Tomestone of Poetics for items exchangeable for gil (e.g. Allagan Platinum/Gold/Silver/Bronze Pieces at an exchange rate of 1 Poetic per 20 gil). BTW, the rate is calculated based on 60/3 (for ARR 'Poetics' minions) and 10,000/500 (a reward for 9 added seals to Wondrous Tails). Historically speaking, a Demicrystal was also sellable to NPC vendors at the same rate. I wouldn't even mind a rate of 10 gil per Poetic if that what it takes to make this happen.

Where can we ask the game devs for such feature? This would save me hours upon hours of painstakingly spending excess Poetics!

I farm Bojza daily to cap tomestones to make gil. It take 10-15 minutes to do this and the profit varies higher than just 20k that you mentioned per the 10gil per poetic. Here is how:
First, go to a website like https://ffxiv.consolegameswiki.com/wiki/Aymark. This is a list of items Aymark sells at Eulmore. Scroll down to crafting mats. Now you can do this with other poetics venders in 4.0 and below areas as Aymark is only a example. Now go to a MB and compare the prices of items on his sell list. Once discovered, take the highest priced item you found on the MB he or any poetics vender sells for crafting, buy in bulk then sell it. The MB is always in flux, yet doing this once you cap and then selling via your retainer yields amazing results. Just to give you a idea of the profit, about 9 days ago as of this posting...I sold nearly 2 stacks of Dwarven Chromite on the MB for around 90-120k. Of course prices vary per server, plus or minus my sold price. Do this every time you cap even if it takes that little bit of time. You will be in the millions in months to come if you do this!
