So how about instead of having tempering with limit rolls you would instead just find recipes as a drop. Kinda like we already do just that this is not a recipe you need to find once but a usable item.
So the idea. You find a scroll with 4 to 6 affixes on it. U can use at the smooth and get 1 of the affixes on your item. The scroll gets destroyed.
If you get a bad affix you will need to find another scroll. You can do that as often as you want. No bricking.
Just more grind. Would also make the loot system deeper that is also lacking.
Not much work needed from blizz. Am ready rework. No free stats. No bricking.
Every one happy.
