"The rewards are heavily going back to the top guys so it's not great for the platform as a whole, in my opinion. People disagree with me on that, usually saying that the large investors deserve the "return". Well their return is so massive that I think they should be economically encouraged to curate with a wider net."

This. It's easy to like rewards when they're pouring in, but every reward attained comes at the cost of an other's rewards, and at this stage Steemit should be investing in growth, which depriving new accounts of rewards definitely doesn't do.

It's not that people able to game the system are somehow nefarious, but that they're gaming the platform out of utility for many, and this shoots themselves in the foot.
