I personally don't think the staking system should be changed yet. There are a lot of variables and the current Hive/Steem user base is too small a sample size to really understand how well a system works.
There's also the effect of education on best practice, general sentiment on the 'right' way to use certain features (e.i downvotes)
I personally think right now we should be marketing and fixing the issue of onboarding and education as to the use of blockchain tech. Making it easier for the average person to at least get onboard.
Creating an account is difficult with the cost and or wait time being a turn off for most. Key management can alienate a lot of people too. There's a lot of area we need to tackle all at once.
I personally prefer the current system as is, perhaps some tweaks are in order sometime in the future.
