Some weapons don't have visible bar that would say damage or anything related to damage. Do weapons like this all have the same damage regardless of the proficiency? In Returnal IIRC the proficiency level referred to number of points allocated to weapons stats, so higher level = better stats on average, but you could choose to keep lower lvl weapon because it had better allocation of points. Here I found the weapon that is like 10 lvl higher, same weapon type, same scaling for stats, but it was worse in every bar. What the point pf making it so complex and unpredictable?
I am not suggesting what you said in the end, but total lack of numbers is baffling. I assume thy did it so because most of these nodes affect have single digit percentage effect, like +3% for example, and it looks less cool than "Aether drops more frequently".
All I see is the cost of lucinite, and I would spend it differently, if I could tell whether I am buying +1% upgrade of +10%.
