I don't think Fupa realizes other servers aren't like Siren where there is a constant supply of fire geodes on the AH. Where they're coming from? I donno, probably people getting them in exp pts and selling them to goldsmiths rather than bother with a fire path weapon. I've been farming flame geodes whenever firesday lines up with my play time, and even with TH7-8 killing over 100 mobs, I'll sometimes get 0. That's less than 1% drop rate on day. It's just the random number generator, and if you get 1 geode or 3 or none at all it's just dumb luck. You can not say you'll get 6 geodes on a day ever. Not solo anyway.
Let's put it this way, if Strength was based on the water element instead of fire, no one would be complaining about the lack of fire weather. Aqua geodes are a dime a dozen. They can be farmed actively in the Alzadaal undersea ruins at any time, and rainy weather is extremely common. So common, in fact, that it is the bane of anyone's existence that tries to get an Ark Pentasphere. If Strength was based on water instead of fire, aqua geodes would be expensive, but at least people could farm them if they so chose. Please note I'm not asking for strength to be based on water, I'm just using it as an example of how fire weather should be and how unbalanced it is. I highly doubt when SE first designed the zoned they envisioned good melee weapons being based on the frequency of fire weather.
