About HQ Levels and Difficulty Tiers, I think it doesn't just apply to events but normal world sorties as well. It does makes sense though, I just played this game 2 days ago and it's mentioned everywhere that CL, and even CVL and CA drops in 1-1 ~ 1-4 (well, maybe only CL in 1-1 and 1-2), but all I got is DD every single time. (even with an S score in all those boss nodes)

But the good thing is, I keep getting better DDs with an HQ lvl increase, on the first day (HQ lvl 1) I only got literally the same dozens of kanmusu such as Hatsuyuki or Isonami, but now I get like 20 different DDs for those same nodes and maps, my HQ lvl is currently 7.

So yeah, this game will naturally gives you a better reward over time the better your HQ lvl is (as mentioned in this page above), just as much as it will send you to a better node, the better your fleet is.
