When people say they don't want exclusives, they don't mean things like The Necromancer being only awarded to those who reach floor 200 of PotD solo. They don't mean Ultimate weapons. They don't mean Hunt mounts or any reward like that which might be locked behind a challenge or a grind, but is theoretically available to everyone.
They mean time-limited and placement-limited exclusives which by design can not be gained by everyone at least in theory.
It would be disingenuous of me to say that you only want to get top 100 rewards back because you - as a skilled PvP enjoyer - want something nobody else can have. Not only because you didn't even ask for limited exclusives of that nature if I understand you correctly, but also because I would be reading into your mind as to what your motivation is.
So please don't read into people's minds like that. There is almost nobody in the world who would argue that Necromancer should not be gated by soloing palace and there's almost nobody against exclusive Ranked CC rewards - it's time- and placement-limited generic character customization rewards that are being argued against.
Don't read into people's minds like that. It might very well be that the people who just so happen to get the top 100 seasonal rewards actually do care about the health of the game mode and truly believe that such rewards are healthy for the game. I disagree with that notion, but to discredit their character like that is to end up with a discussion like the following:
One side: Wants everything for everyone allegedly but WOULD have rewards limited to themselves if they weren't so incapable, so they demand handouts as their only way of getting anything. CC will die because nothing is to be gained by achieving greatness.
Other side: Allegedly wants everything for themselves and others not to have shit. Only cares about virtual prestige and only achieves greatness to take away from others. Sociopaths are the only remaining contenders for top 100.
If these are the real motivations behind this whole discussion, then the health of the game mode is not actually the subject and just an excuse. These are mad positions to hold.
