You can’t argue that the cloth feet leggo that let you cast on the move occasionally were good. Those were not because good casters learned when and where to stand.
Only certain leggos were good because Blizzard made them good or overtuned. Maybe you had good luck, or maybe you just dealt with what you were given. That doesn’t mean the system was any good. Rng legendaries were a terrible system. You can never convince me that they were good. Rng loot in general was taken, in part, from this system for BFA and SL.
The system was only okay when, after all was basically said and done, you got the currency to trade for a legendary. During the Argus patch.
I’ll repeat. The rng legendary system is, objectively bad. Because you have to deal with other people that want optimization. It’s part of the whole mm part of mmo - massive multi-player. If your guild leader was more chill, cool. Same fit your raid leader. Never ran into anyone using the generic legendary items that did good. Not just didn’t preform to minimum of what we asked, but just didn’t play well in motivation. Stood in the fire and didn’t do mechanics.
I’m not even saying those people weren’t trying to get carried or trolling. If you needed help with your class, guides existed. But of you were screwed by your rng legendary item, that did not help you. At all.
It would not be as much an issue if you just did world quests, and mostly stuck to yourself. But that didn’t sound very…mm of the mmo to me. If that’s good you like to play, solo, go for it. Rng loot is bad. But bring able to target certain pieces is bad. Legendary items should never be on an rng track. It invites people to turn their nose up at others for no reason needed.
