I don't know how anyone would think the Water Temple is hard. It can be confusing, because I remember running in circles a few times, but there's nothing remotely hard about it. Even Dark Link topples over pretty easily. But that pretty much goes for the entirety of OoT. Link is practically a powerhouse and there's no penalty for anything.
