To be honest, 99% of the champions out aren't very good.
I haven't played champion as long as many of them but I really expect those who have played for a year to know simple tricks to surviving.
The number of them that keep Fervour on when getting targetted is ridiculous, you might as well be stunned if you keep Fervour on.
I have seen no one and I mean no one, turns Fervour off and switch to a shield for defensive measures. It only works wonders and I have survived attacks that should have been instant deaths.
