That should be plenty, especially if you pop a Battle Rage on top of it. You could even up the difficulty more.
I've been playing Nightmare from the start. It's all about offense and moving in this game seems like, if you dabble too long its easy to die if there's more than 2-3 enemies. The flying fortresses in ED were killer with my build at that difficulty.
Also have maxed death blow (with jewelry help) with +7 crit on belt and rings giving me 51% critical chance total. With level 11 rush attack, it's usually enough to one hit most of the enemies ive come across in FOV so far. With battle rage L14 its about 60% increase (though description says 150% increase) so base is around 2185-2269.
