I get the feeling they intentionally reduced the spawn rate of star metal as part of this overall effort to re-balance and nerf Silent Legion armor by changing the recipe and tying it to star metal because some PVP players are always complaining that SL armor is OP. But SL armor isn’t OP in single player because you have to kill world bosses like the Undead Dragon by yourself, and you have to survive large NPC camps to acquire certain crafting thralls.
I usually make my main base around the center of the desert near the dogs of the desert and the Mitra temple, and I used to see meteorites across the sky from that point all the time. It was a nice effect that added to the atmosphere of the game. But I’ve not seen a shower in quite awhile. I can still stand around in the far north for an hour or two, and one will eventually show up. But then I can usually only find one node whereas I used to be able to find more than I could actually carry if mined.
Even if I had way too much star metal than I could ever use, I still found it the most fun to mine star metal over the other ores. But now, star metal has become boring, and the environment has become more boring. All this re-balancing has become myopic IMO and overly focused on PVP competition and complaints at the expense of single player and PVE playing styles.
