I spent over 2M gold on guild contributions over time and now have no gold for kingdom leveling, while 122kx18 is needed… Meanwhile I’m swimming in iron keys that there’s no much point to open in the first place and the opening interface makes me not even think about it.
However a simple change would cure most of my grief: the kingdom leveling could have an alternative price in keys. Using the same 1000g = 1 key as buying.
That would also restore the feature that guild contribution is an actual benefit to players.
