So... This is the "improved encounter design"?

[Raikai]

we're talking about difficulty because it's a risk to implement new mechanics they're not used to, it can either result as being too hard or too easy

and my guess is they didn't want the first tier to be harder or easier, so they didn't implement those new kind of mech

But why it's a risk now, but not a risk in 7.2, since this is targeted just to a certain demographic of High End duty players? Especially when the 3 raid tiers in practice work as standalone entities, because you don't need to experience the first to get to the second or the third... I remember I started tackling Savage Fights more seriously in the second tier of Endwalker. I just feel that the best time to introduce change is always in the beginning of something.
