Masterworking gets a pass from most people because they don’t interact with it, but it’s just as bad (if not worse) than tempering because you can be stuck in infinite loop of bad masterworks.
And the cost of masterworking is insane for the average player.
1 IH on T4 only gives you enough gold to reforge your masterwork once, and that’s currently the best way to farm gold. It’s insane that they think anyone will interact with these systems who isn’t an RMTer or trading with RMT/dupers.
