I would only agree with this if it were a Tournament deciding who progresses to the Elite 4. Otherwise, no. The Elite 4 is designed to put your skills as a trainer to the test, and thus is made to be difficult.
People complain about the 10 level gap between the last Gym Leader and the first member of the Elite 4. I actually wish the gap was larger and gave us more to work for. That way we feel a greater sense of accomplishment once we've beaten them.
I beat the E4 on Pearl first time, with only 3 fainted Pokemon, having used about 1 Revive and only 3 Full Restores in the entire run. Needless to say, I was very, very dissapointed. I expected a lot more out of them.
I'd be very happy if the Champion's Pokemon peaked at Level 75 or so on the first challenge.
