When SL first came out, after two weeks I had a full stack of wandering stars and had a very hard time scraping up enough of the other green RC mats to do the dailies. After the patch to change the rates, but not the dailies cost, at 28 stars a day, I blew through that stack in a few days. When the dallies were changed to be more in line with other professions in terms of costs, that helped, but it didn't replenish my stock. At the moment, I have, after today's dailies and opening of reward boxes and breaking of greens from the days questing, 13 wandering stars. I have almost full stacks of the other green RC mats.
This. Is. Not. Balanced! I am very tentative about making runes for myself let alone my guildies, trying to balance getting master and grandmaster marks for recipes against the needs to have better stats to survive experts more easily.
And that's just the issues with the greens. Two patches ago, I stopped getting branching stars from blue items. After breaking 4 and getting nothing by green mats, and hearing other Runecrafters in the same boat, I started storing blue items against a patch fixing the issue. The last one did, sort of. I started getting branching stars again, but the underlying issue remained. Breaking down 8 blue items, essences and armors both, I got a grand total of 5! branching stars. Had I sold the items instead, I would have netted around 12-15 plat. Some runes take 4 branching stars each. The daily workorders often take 4.
Old world, breaking lvl 50 blues would get me 1-3 crystals usually. Rarely I'd get only greens. Maybe 5% of the time at worst. New world, I'm lucky to get branching stars 60% of the time, and I've only seen two drop from one item once. This is not fun. This is horrifically frustrating. I can usually manage to acquire a blue item or two a day from hunt rifts, random drops, or the chronicle, but with the current drop rates, that's not enough to do dailys and help my guildies out.
Please, please, please look at the rates for wandering stars and branching stars. I think only the artificers are experiencing the same sort of pain, with trying to get enough gems for their stuff right now.
