Pure RNG is the worst thing ever.

[Jamein]

The RNG in this game is childs play compared to others.

That being said, the relic RNG is fine, yes its still a boring system that isn't fun at all, but that's what you get for getting the best weapon not from raids. The RNG isn't the problem, it's the quest itself that's boring as hell. Put that same RNG in something that's fun to do and we're good. Unfortunately, there are two ways to make something take longer in an MMO, make it a long ass grind where you get minimal returns towards something (Light farming) or make it RNG. The RNG aspect tends to infuriate less players overall, because it's only the people who get god awful RNG that are the vocal ones. Which is why we see the complaints, my Zodiac took me 72 dungeon runs, so with that in mind I wasn't going to complain it wasn't bad.

Now as for the RNG in raids, that needs to be fixed, there should be a token system, so that even if you get your clears but are unlucky on the drops, you can at least get a token towards an item of gear so it's not a complete and utter waste. That way everyone is progressing.
