Alright, so let's assume they don't want to change the drop rates.

Let's think about why they wouldn't want to change it.
1. Lower drop rates means more playtime > more money every month for SE

2. Since the price is high, this means people will have to get money to buy the geodes > more playtime > more money for SE.

3. People are still actively needing geodes, so therefore its still a relevant issue, so therefore it needs to not be "fixed" until it no longer affects the estimated playtime of a large % of players. Kings were not "fixed" until their gear was 99% obsolete. Teleporting to sky was not fixed until that zone was dead. The scaling of CoP did not happen until the content was used up.

4. It does not negatively affect the gameplay of others. SE is very quick to adjust (nerf) jobs that are overpowered or bugged once it is known and understood. The Catastrophe nerf, Penta spam, the npc in Norg, The Ranger nerf, The Ukon nerf. Salvage bans. Why? Because this affects the balance of the game. It affects how fast people can make money, and what jobs are considered "useless". Which prevents players from quitting the game.

Bottom line - Low drop rates and time sinks make them money. The developers know this. It's better to adjust issues after they serve no purpose to appear to be making positive changes to the game, than to change current issues that only serve to affect their monthly revenue.
In my opinion it's why they are extremely careful not to adjust anything current that affects all players ability to enjoy the game. Legion for example sucks, because it is hard. However it is still active content. Hard content will take longer to clear than easy content. This is why they are willing to add music features, but not adjust difficulty.

I don't expect them to "fix" the geode drop rates. They know the drop rates are skewed in their favor.
Why give that up??
