I'm not game developer, i just play the games. I can tell you RNG that fails this much makes for a game that will fail. it makes people rage quit and go find different games to play. RNG is something new players and lower level should have to worry about if they are just trying to craft tier 1 items. To many games right now have a very extensive hard to master skill tree and that is great, but more simpler skill systems have create more fun game. Key word here is FUN.
