Irons were able to use SoF before and it ruined the whole gameplay. Because you can get a lucky divine when you are level 3 and your endgame is completed + you can get xp lamps.
Removing SoF was a great move, so i believe the best is letting it the way it be.
Not if you remove some RNG based reqs, you throw the quests in, maybe 1/2k ckeys, achievements, à certain amount of vote/challenges done and others things
If your inventory is full and you wanna make darts, you will be able to receive xp - a message that your inventory is full but without the darts which is supposed to not let you do it since your inventory is full and you can't receive them.
