Hello,
Thank you for you message.
However we are not planning on integrating these items to Prestige nor making them time-less. They are mostly QoL/time-savers with many alternative options to obtain gold/speed via other systems (guilds, fishing, housing, auto looting settings/addons etc.). They are in the end optional features that aren't required to reach high ranking positions, especially some of them didn't even exist before and added just as requested Quality of Life demand. Moreover, some of these are even scheduled for changes due that.
Prestige is also planned in next season on changing prices from PNC to diamonds for wider availability as well as revised rewards. Currently price is scaled based on left season time, updated every 10 days.
CoA provides wide possibilities to obtain diamonds for free via Auction House and game activities, some tips can be found here: https://wiki.chroniclesofarcad…ers/tips-to-earn-diamonds
We are also planning on introducing contests providing Reward Coins and extra PNC -> diamonds bonuses soon.
Greetings
