Oh, and that will happen. It will happen again and again and again and again. I found a 5L thicket bow at one point and decided to just keep chaosing it until I got a nice roll and then build a ranger around it. 50+ chaos orbs later, I hadn't got a single set of remotely usable stats. Not even just no great rolls but literally no rolls that yielded a weapon that could possibly be used at all.
Rolling up a good item takes such a laughably absurd and broken amount of currency, it's utterly retarded. You know those really good crafted rares? It easily takes 30+ exalted and eternal orbs to make one, as well as thousands of alterations and dozens of regals to get the first affixes. This would very literally take years to get by yourself. The currency you get from farming for two months is statistically almost guaranteed to yield you nothing good whatsoever because the maths are so overwhelmingly against you and the system is blatantly designed to only be available to trade junkies and RMTers (which is apparently becoming a big problem -- wonder why.)
I started the new leagues out with a character that I intended to farm with until I had the pieces to start up a new build, and that simply never happened. After a month, I still hadn't found a single build-enabling item or enough decent rares to feel ready for any worthwhile build. In a month I never found a good bow, never found a good wand or caster dagger, never found a high-ES chest, never found that trapper belt or Searing Touch or anything like that which would have been the centerpiece of a build. I got a few good rares, a few good uniques, but just nowhere near enough to justify the kind of time it takes to get anywhere in this game. The tuning of time vs. rewards in PoE is so bizarrely bad that it's almost insulting.
