That said the bitcoin block find method does not seem fare, highest pool hashrate win the majority. Why can they not make a method that selects pools at random to evenly distribute the blocks between pools, no matter the hash-rates?
Proof of work is bitcoin's greatest strength and its greatest Achilles heel. There is no fair way to do what you ask. Even a completely redesigned proof mechanism that attempts to do what you ask would be exploitable. This has been debated to death since its inception by much smarter people than me.
