In regards to the greater??? and unstable???, I think it would be great if we could convert the unstable ??? into greater ???.
It took me 10min-15min to start a surge with unstables ??? because the crafting is really slow.
Having to craft 500 of these only adds to the stress and it’s no fun. I can’t remember the exact time but this took forever, and I do remember that once passed 500 focus(250 unstable) the shrine appears on the map and people will steal the unstables from the shrine before you can reach 1000 focus. It’s ridiculous.
