That doesn't even make any sense. Sure you'll lose evasion, but that's not the end of the world. The only place where you really need it is in normal questing, and against easy raid bosses. And even then, 500ish hp should be more than enough to make sure you stay alive.
And even if that is a big problem, just use a fire/air/air lob weapon in the off hand, and a holy burst, silver of gbane or lighting II in the main hand.
