Please consider increasing possible Affix Tier levels for dropped items.(not shop) Something around T7 should be good. It should be quite rare though.
Rune of removal will actually have a purpose now. Imagine an item dropped with 2 prefixes, one is T7 that you want and one is useless. You gamble it with removal and in case of success continue gambling further with crafring.
Loot hunt will be much more exiting. At higher levels i rarely check dropped items, as i know that my crafted gear is just better. Having a possibility to have affix tier that can’t be crafted can make loot exiting again.
