I am not sure how much you used or experienced the Glyph Of Chaos yet, but the chances of actually getting your desired affix are very high in a lot of cases, depending on the item slot.
There are a few important things:
- You cannot roll the same affix again
- You cannot roll a duplicate affix (if you already have a 2nd affix on the prefix/suffix you want to roll)
Depending on the item slot, there are usually 15-20 affixes within a given pool, some item slots even have sub-10 or fewer than 15 at least.
Just to give you a few examples: Wands have 7 Suffixes, meaning that you have a 1 in 5 chance, to roll the desired suffix (given, that you have a 2nd suffix already)
Another good example are Shield Prefixes, there are only 10, so that means you have a 1 in 8 chance in rolling the desired prefix (given you already have a 2nd prefix)
Boots have 7 prefixes as well(same exampels as wand suffixes)
Given that you can re-roll up to 4 times from T1 to T5, there is a very high chance of getting your desired affix in a lot of cases.
There are also a few negative outliers here, mainly Helmet, Body and Relic prefixes, due to the high number of class specific affixes.
Also Amulet and Ring Prefixes are ~30+
So it’s highly dependant on the item slot you are using glyph of chaos here and if you don’t like that kind of RNG based crafting, you can take those item slots into consideration for your loot filter rules.
All of this is not only theoretical, but I have crafted dozens of good items with the glyph of chaos, so again: I like Glyph Of Chaos!
I just think, that critical success in this particular case evokes similar “feelsbad” moments, than some of the other things that could happen in the old crafting system.
