Impale crit cyclone..need help with Ascendancy

Hello All Slayers

I'm very much in doubt of which Ascendancy notes to take

Now I have Brutal Fervour + Bane of Legends

I use Vaal Pact from Atziri Gloves (can't afford the Legacy version)

Would it be better to switch to Overwhelm and Impact or?


suggestions (and why) are very much appreciated, and please have a look
at my charater setup :-)

thanks
