It is the pre-Dragonflight times where we all want to throw our wishes in Blizzard’s general direction and hope something sticks. This also needs to be said.
If a system needs a catch-up mechanic, it is a bad system and it should not be shipped with the game. Catching up is perfectly fine - players now can skip whole expansions if they wanted. Nothing wrong with that. With gear seasons, players can jump from 160 questing ilvl to 239 in no time. All of that is organic catch up that comes from community progress and the ability to carry people. This is fine.
What’s not fine is having to boost drop rates for new players, boosting rewards and renown levels as time goes on. Because this punishes people who play on release - the same reward MUST be obtained, but you can do it in 1/5th the time. You could play for months getting your 2-3 renown levels a week, or you can play right now, getting 2-3 renown levels an hour.
This can all be avoided by removing weekly and daily timegates and making time-gated systems not mandatory, like how Archivist research or Pocopoc research works. These systems don’t need a catch up mechanic, because they are side activities for people to partake in at their leisure. And in fairness - this is what makes me want to engage with these systems.
