Yes and no. We can't ignore the fact that the accessories made from flame geodes are also in high demand, unlike the accessories made from breeze geodes.
The price of flame geodes would probably decrease, but I doubt it would go as far down as breezes are. Using my server as an example (Sylph), flame geodes are 60-70k now, while breeze geodes are 15-20k, I think we can realistically expect a drop in flame geode prices to something like 30-35k a piece. However, if fire weather is changed, we will have a much more realistic option of actually going to one of the volcanoes and farm the geodes there ourselves, instead of camping the auction house.
You could simply check a weather NPC and take note of when you've got 2-3 ingame days of "frequent heatwaves" or something coming near the volcanoes, then teleport out and knock yourself out.
How you could call it "lazy" to want to do 3 hours of geode farming in one go rather than one hour of geode farming with 7 hours of waiting in between, I don't know. I also don't get how this would be more lazy than sitting at the AH with your wallet full of gil, waiting for the next geode to pop up.
