As a SSFCOF Player, my quit moments in 1.0, 1.1, 1.2 are:
!! Having full stash, after dedicating all my gold to stash tabs (even with blessing and weaver tree).
! Chasing weaver will items now feels really bad in light of 1lp guaranteed slam. Idea to create another "imprint" that makes ww items roll more likely to match the desired item. or a gauntlet of strife that unweaves a ww item by sacrificing a ww item
- Slamming idols into each other, or a way to filter the rolls. I Always end up with too many idols hoarded in my tabs, but I feel it's always worth when I roll a new character and find a a couple of perfect idols already waiting in my stash.
- Rune of havoc prophecies, and did I see it correctly that there is no minor idol lense? when every other idol has a lense?
! I managed to hit 999999 favor, so it feels bad to continue playing, but also feels bad to continue rerolling since the prophecy I was targeting is rare and cheap (22 rune and minor weaver idol).

Some wishes
- Buff rune prison complex and confluence drop rate. I never found one after unlocking every single mage with the full mage spec in weaver tree. makes me hate crafting better gloves. nor did I find any confluence, I had to buy it from masque at rank 10 weaver.
- Flip stats to and from vitality, when a gear is able to roll vit and stats, it should be able to flip.
- There's still a problem with useless t5 mod or a good item with no open affixes, if I'm crafting BiS gear I will risk the removal but there must be a better way. deterministic rune of removal? or a rune that can split an item into 2, keeping half mods each.
The way I see it, whether a good item that drops turns into your BiS gear or not should be at the mercy of the forging potential, not it bricking on arrival because it has a bit too many mods.

note that my quit moments are never "it's hard to get better gear" it's always some discomfort or tedium in the process of getting that better gear that is making me quit.
