I wouldn't call the content "broken". Broken is a term you would use for glitches/bugs in the game, for example; proteus prime will bug out and drop 1 item instead of the original amount of items it's supposed to drop. A better word for not getting the drop you want is...... Bad....... Luck. I'm probably gonna get blasted for saying thisIt depends. When something critical is broken, I think they should fix it. But because it benefits them, they put it as a low priority.That actually seems fair enough to me, if u have a schedule to keep then u have a schedule to keep, I guess every company has targets they need to reach.
One such example is the Proteus Prime encounter - lots of plat items used for very little or no reward. It's definitely broken but they won't change it because it puts money in the OTM bank.
It's broken because the reward for killing it is nowhere enough compared to the effort to do so. Someday when you have first-hand experience on what we're talking about, you'll see...and you won't call it bad luck.
