Can we please have a developer look at this thread? I think it requires addressing.
TL;DR - Scroll to the foot of the post.
The quests for the 'Ergon Weapons', Idris and Epeolatry, are far too taxing in comparison to relic, mythic, and empyrean weapons (not so much the latter in later stages): Specifically the final stage of the quest and the 9999 High-Purity Bayld requirement involved.
The pre-requisites for both are perfectly adequate, having Legend in all coalitions for Ergons and having Captain rank for Mythics, but I must stress that the problem is the cost and availability of High-Purity Bayld in comparison to Alexandrite. As it stands across most servers an Ergon weapon will cost, considering an average price of 35k (some going for as much as 50k on some servers) per High-Purity Bayld and with 13099 being required, a whopping 458m. Now, compare that to a Mythic weapon with Alexandrite now hovering around 7k per piece and with 30000 being required bringing that total to around 210m. In reality the figure required for a mythic would actually be lower considering that a player can solo farm Salvage for their own Alexandrite and do other farming on the side (Dynamis, Voidwatch, and selling High-Purity Bayld) to buy other pieces, so really this figure will be around 130~150m.
I would therefore suggest that developers either make High-Purity Bayld a lot more available through various means or reduce the quantity needed for the final stage of the upgrade process. Both measures, increasing supply and reducing requirement, should not be implemented as some challenge should remain present - just one will suffice. As it stands the quantity needed per stage increases as such: 100 - 500 - 2500 - 9999. The first three phases, in addition to other necessary requirements such as Skirmish Stones and Delve materials, are perfectly reasonable, but the final stage is such a massive spike in difficulty that it is baffling. You are literally looking at 350m for THE FINAL STAGE ALONE when the first three stages amount to roughly 100m. No matter how you slice it that is an insane spike in expectation.
The solution I would suggest is that the number of High-Purity Bayld required for the final stage be cut in half to a figure around 5000 making the grand total required 8100. This would put the total cost for an Ergon to around 300m, still expensive but certainly more reasonable. As fewer and fewer people could potentially do Adoulin content, the source of an already constricted supply, with impending updates taking players outside of the source the price of High-Purity Bayld could only increase as fewer would enter circulation. This is something else that requires consideration.
Now, developers have gone on record saying that the immense difficulty in getting an Ergon weapon is entirely intentional because they are "extremely strong" weapons.
Okay, let's take this viewpoint and run with it. So, these are meant to be "extremely strong" weapons are they? So, tell me... How is a Samurai using a Tsurumaru, which is an extremely common thing, able to utterly flatten an Epeolatry Rune Fencer in terms of damage output? On that note, how is any damage-dealing job using a Mythic weapon able to completely outdo the weapon for what equates to less-than-half of the effort invested? Sure, one could say that the Epeolatry is meant to be a weapon for tanking but then again how much does an Ochain and Burtgang set a career Paladin back by? Nowhere near as much. Also consider how many times you have honestly gone out of your way to bring a Rune Fencer over a Paladin for high-end endgame content such as Very Difficult battlefields, Incursion, and practically anything that requires a tank? The fact is that a Paladin can completely outdo a Rune Fencer on most content for a mere fraction of the effort and nowhere near the cost. If a job requires a 450m item to even remotely compete then something is very wrong with the job itself, but that is a matter for another thread.
Then there is the little fact that Dimidiation, the weapon skill tied to the aftermath effect of the Epeolatry, does not gain a boost in damage like a Mythic's equivalent weapon skill does? ...Really? After climbing such a massive hill you're going to do that to the climber? I doubt that alleviating these problems would not solve the problem that the job is practically useless for anything high-end.
Now, with regards to the Idris my hands are held high. This one is tricky to balance. While the Epeolatry nowhere near warrants its current price tag one could reasonably argue that the Idris certainly does. As any Idris owner would tell you the weapon is a MASSIVE boon for the Geomancer job and when used under the effects of Bolster it is downright absurd. I suppose that the counter-balance for the absurdity of Idris is that a Geomancer is still restricted to one mediocre buff/debuff (Entrust), one mid-power buff/debuff (Indiclosure), and one high power buff/debuff that is reliant upon Job Abilities and that can be destroyed by monster attacks (Geoclosure). I would still suggest that the Idris be made more available but I'd say that at the same time Riftcinder be made more available so more Bards can gain access to the four-song Empyrean Harp.
-----------
In conclusion, I propose that the amount of High-Purity Bayld required for the final stage of the two Ergon quests be reduced from 9999 to 5000. This would make the difficulty increases in the quest more consistent and would help 'balance' the two weapons with their Mythic counterparts. I also propose that if you plan on introducing content outside of Adoulin areas and that do not provide a supply of High-Purity Bayld that you drastically increase the supply of the same within existing content such as make Wildskeeper Reive Naakuals drop an Aged Box [Bayld] 100% of the time and increase the minimum received from a box and increase the maximum received from a box to an amount roughly half of a Linen Coin Purse.
Thank you for your time.
