Dynamic ember drop suggestion

I just came up with an idea while I was farming my 7th pestilence area. Which I realised that after some point ember drops are getting less when you spam pestilence its same for the crucible as well as I observed (120hrs of play together update). So I thoutght it would be better when one endgame content start to give less ember it increases other farm methods ember drop rate such as general gathering (mining, digging, fishing etc) and crucible and chest runs. So this way players will have to decide to change their farming content dynamically which prevent one boring and continious content spam and forces the player to farm other contents in the game. It also can have a cooldown similar with pestilence. Idk I’m just cooking this idea on my mind for last 10 mins lets brainstorm on this.
