My biggest gripe with the exp scaling currently (as an Ironmeme having to engage with all sorts of odd content from release)
Theres just simply no reason for everything to be better. Rewards get people to go there, the exp rates should be a reason to stay there for a while longer.
There would absolutely be no difference in ed3 engagement (full clears) if you literally x0.1 the exp rates. By having newer content offer insane exp rewards (we're talking 1 kill = 1 hour over in osrs) it just nukes any other content with some cool rewards.
Hunter got an integrity change for being too busted when it was a high input method that made those rates achievable, now we have full AFK methods that blow that out of the water.
Why did you guys go from 100k exp/hour to 200k to 500k to 1m+/hr instead of just going with 100k -> 120k -> 150k etc etc.
This also frees up plenty of reward space in TH as it doesnt have to compete with absurd exp rates to warrant the purchas...
