Firstly: Hats off to those that have succeeded in reaching max RP within the game as it is.
Nonetheless the grind would be a little supported by the possibility to exchange or forge the rank up materials, like the upgrade materials for equipment or charms.
This way there would be a bigger incentive to spend gold, guild accolades, arena crests and crimson souls to for e. g. buy malachite to forge or exchange for cobalt vice-versa for fehu to laguz.
The impact would not be as big to cause a ruckus, but slightly noticeable:
There are 50 malachite available to purchase each week (arena & guild shop) and if the exchange or forge rate was 8 malachite -> 1 cobalt, that would sum up to 6,25 Cobalt per week.
Happy to receive additional remarks from fellow players!
Thanks and cheers
