Blade and soul Q/A

Another question; is there a way to upgrade your weapon without having to feed it soulstones, they are 30s+ right now and I'm not willing to feed it dozens of stones just to get to a breakthrough where I'll need to feed it even more. I fed it Infernal gear as long as I could but it's over the level cap for that after siren, and all the current tier of weapons require soulstones as a secondary material. How are people not going broke before they even get to the break/trans?
