Yeah, this is my primary thoughts on SSF crafting.
-Bring back Alterations. This allows rerolling of white>blue bases. instead of filling up inventory with white bases..
-SSF currency trade/vendor recipe. SSF needs to be able to convert one currency into another. you could do this in PoE1 via vendors.
-Essences 10x more common. either, see them every map/zone in campaign, or they litterally drop 10x more shards. Essances are worse in poe2 then 1.. how? they add this deterministic crafting idea, then make them so rare, they might as well not exist.
-Omens. same problem. introduced ritual in act 1. we never see it again till maps. theres 17 kinds of omens. Ritual needs to show up throughout the campaign. Omens need to be a guaranteed favor option. 1-2 per. between 17 kinds, and being consumed by use, they would still always be in demand, and not enough. omens would solve much of the problems.. if they were 10x more common.
(also fix the map generation, and unit collision/stun on spawn issues)
-ability to replace runes.
