It's the absurd level of RNG that CG included in this raid. I have gotten 3.6 with the QA team but also gotten 500,000 from the QA team that does the same Tier 7 every time. Maybe CG didn't expect the ridiculous amount of RNG in this raid, but that just means they didn't actually play it. They just plugged in their 16 mil GP test account and pressed "sim" so they could say, "yep, no problem!"
CG appears to just be looking for us to waste time being in the game so they can say, "look at how many hours our players spend in game everyday!" This raid is worse than the CPIT when we had to have the entire guild all drop damage at the same time.
Don't count on anything to change with it though, they've been concerned about the next raid for at least 4 or 5 months. If we had something that benefit us (like the B1 stacking glitch) they'd fix it. They didn't fix the B2 lead option because it requires players to bump 5 characters to R8 we wouldn't normally bump up.
And next raid it'll be a bunch of new characters we don't use otherwise that they'll expect us to relic up. At least relic'd up characters are somewhat useful for ROTE TB?
