It's always the same thing every expansion
Day 1 - you feel like shit because you lose considerable power each level with your secondary stats tanking into oblivion
Tier 1 - you continue to feel like shit because your secondary stats are low across the board
Tier 2 - you recover a lot of your former secondary stats and your class actually starts to feel okay to play
Tier 3 - probably the perfect spot as far as secondary stats go
Tier 4 - your secondary stats grow into absurd quantities to the point some of your fundamental class mechanics break
Both Tier 1 and Tier 4 secondary % are horrible.
Please, Ion. Just make a flatter growth curve for secondary stats but make them start at a higher baseline level. No one likes playing their class when it feels like it's handicapped. Or when it's so absurdly scaled that you are just mashing buttons with no thought.
As an example, in this expansion (and I play a hunter) Frenzy management in Uldir was terrible because of the long cooldown on Barbed Shot and low extra Barbed Shot procs. It was so bad to the point it was distracting you from actual boss mechanics because dropping your stacks equated into a huge dps loss.
Now in Ny'alotha, thanks to stupid amounts of crit and haste you can basically ignore the existence of Frenzy stacks because you can just hit Barbed Shot on cooldown and still maintain 3 stacks >90% of the time.
Just find a sweet spot for secondary stats and keep them floating around that number. No need for wild swings from 10% crit at the beginning of the expansion to 50% crit towards the end.
