OK to the people saying it won’t make much difference, you are wrong.
Refine change was possibly the most dramatic change to the eve universe that ever happened, it had dramatic effects for both player behiviour & CCP’s monetisation of eve.
Previously you could perfectly refine at 100%, meaning no product in eve could sell for less than its base components without being bought & melted for profit, meaning no player could produce materials at values less than base component prices without making stark hard red losses. This was reality shattering for many players, they come to eve to feel like winners not the irl chumps they are.
CCP then made refine losses meaning normal IQ players could no longer simply buy from the fantasist at below base price & take 100% of margin, no matter how small they were. Sometimes so small you had to wait for market swing.
This refine losses is the % that makes poker a popular pastime. Despite not being a good poker player “shark” you as a “fish” still have a blurred perceived % chance of winning against a shark. Sometimes a fish will beat a shark in a game of poker, known as donking. Eve industry has a donkey % where if you squint or go cocktail eyed enough you might be able to blur your losses into profits, this is the game CCP sells you, you pay $ for the distorto vision per 30 day plex.
A ccp’r at some point sat down and brought this game philosophy to eve, I would like someone to name him but might have to wait for the book? I suspect CCP were trained by that Sony dude?
Anyway CCP are writing their own plays now, some of them suicidal.
Allowing players to trade & produce at losses while celebrating them as profits via plex $ purchase defines modern eve. It is literally a pillar of this mmo, every patch change will incorporate it.
