Let’s look at SCL9.
In PVE they reduced the CP from progression from 40 total to 30 (same rewards in the nodes).
In PVP if you play SCL9 you have 24 in progression per event, so that’s a loss of 1 per PVP or 3 a week.
Total loss is 23 CP less if you play in SCL9 than before for one week of events.
Yes there is some make-up with more 4* covers, shards, maybe lucky pulls on Mighty tokens, etc. But they did remove some CP which would obviously make it harder to build a hoard up, especially if you are lower in the game (don’t have all the 4’s champed and most are at low levels).
I don’t have PVE 7 & 8 up since I already joined the Hunt, but in PVP you get 20 CP per PVP in 7 and 22 in 8. So the lower you play the less CP you can get.
In 10 vs 9, PVE provides 34 progression CP per event (lost 6 CP) although you can hit the CN now and get one more, so I guess you are down 5, or 10 a week. PVP provides 28 CP so plus 9 for a week, so basically we traded 1 CP from progression play for the assorted goodies if you are playing PVP to the CP.
I’m not sure about sub stuff, but it’s a little lower there as well. Ex: I placed T10 in SCL9 sub 3 and only got 2 CP where before I got 3, if I recall correctly.
Again, I’m not saying “this sucks!” but if your personal goal is hoarding CP you’ll be forced to do it longer than before. The good news is more covers and shards mean you don’t need to pull things to add levels (assuming you gather enough from progression and placement), so maybe some players can keep up with the old hoarding pace or maybe do a little better, depending on who is rewarded and your individual roster.
