Does Gym rework also mean that Top Defenders change?
There is possibility of different motivation loss rates and amount of berries needed to feed them up.
Can't wait for someone to crack the numbers.

I don't even know if defenders matter anymore, all changes seem to favor attack. After the mons lose about 1/3 of their CP they hardly get a chance to use charge moves (except maybe Blissey). Even if they do get off a charge move the damage is so dramatically lowered it's hardly worth dodging. It appears to me that the point is volume of defenders (20 per) over quality. Work on improving your attackers for raids.
For example, I used some specialists to take out each mon the first pass. After that a lev 31 Exeg and 31 Vap (maybe throw in a Machamp) can take it the rest of the way down without using any revives.
