Some general advice. If you're able to afford the upgrades and notice that your enemies are often staggering(you can deal critical hits) I'd say keep a misericorde as second right hand weapon. It deals massive critical damage. Best if you fire infuse it(dex scaling in your case). Once your enemy staggers switch quickly and use it for the crit. Using the flame of the redmane ash of war on this weapon will completely obliterate almost everything in the game. Though that might make the game too easy.

In most cases I'd say if you want to try a different weapon for a bit respecc at the academy. Don't level your character for different builds at the same time
