Overprepared is Overdone!

If you are being upset, or unable to win, it means your characters are at low gear or you aren't using the right data disks

That's a lie. How many times do I have to say it. Nothing about being forced to sit out for an entire round for 90% of battles is in any way considered a challenge. You're telling people to run normal or easy if they don't have the gear for it. Guess what, I am running it on normal and my team is geared and modded way beyond the recommended amount.
Then you tell us to use better data disks. That's such a laugh when you know for a fact it's rng. All I ever get are useless data disks. Especially when you just start the event and you're still in phase 2. There are not enough options to get what is needed because it's all locked behind rng. With every conquest they make it harder and harder to get any useful data disks. I have gone entire events without ever getting any useful data disks. This is with going the hard path for greater selection. It's all the same garbage. I don't normally see anything good until the last phase and a half of the event where they slightly increase the odds of better disks after the final boss fights.
