Luck is terrible stat and should not be a stat to rely on. This is a terrible mechanic to have in any game and creates the problem of “Do you want to be stronger or find more/better things?” Luck has become such an important stat at lvl 60+ that if you don’t find a piece of gear with luck and perfect stats, pre 600 gear, it’s basically not worth having.
The game should have been designed in a fashion where players can obtain their items by fulfilling requirements if not by the drop rate set by the designer. If this were the case, gameplay would be more fun and rewarding. Instead we, the players, have to farm/craft gear which also has luck just in order to replace older gear with less luck.
Now I know suggesting this change is huge and would take months to revamp, but I strongly believe the Luck Stat brings the quality of the game down by significant amount and brings no joy to the player(s).
Luck is a design which creates more problems than it solves.
