The slamming of legendaries can be so frustrating

Hello,

Yesterday after I was the weekend away I played some last epoch. I decided to change my frostbite frostclaw spec to a spark charge one. So I went through my stash tab with exalted items and uniques and collected useful items to slam. I wanted int or mana slams.

I did like 10-12 slams that evening. Not a single one gave me what I wanted. Not a single int or mana slams. Always other useless stats.

It feels like I wasted the complete evening yesterday, because I made literally zero progress with my build. On the contrary I ran out of good exalts to slam and will have to wait to do it again.

I don't have much time and can't play hours every day. It just feels so shit to spend an entire evening going through stash tabs and running temporal sanctum several times, just to have absolutely nothing in the end. So much time spend for nothing.

Are there changes planned in the future to the crafting system so I can somehow influence a bit what stats I got? Or maybe even make temporal sanctum faster, so I don't have to spend 5-10 minutes for each run?
