Have to balance crit chance and crit damage. Without crit damage, high crit chance also useless and vice versa. I think a ratio of 1:10 would be just nice.

Like other members said, your wildwood needs a socket with crit damage. Compulsory to have both weapons with sockets for easy 200 crit damage.

Your chest armor re-roll armor to get 3 sockets. Pants reroll vit for sockets. Dont need so high vit I think. You can substitute your vit with something else.

Im running only 303k hp on T3. I sacrifice my vit for my dps.

Lots of your other eq can still be upgraded. Your signet ring lack of dex.

Since when did vit gives dps. You sure you got the facts right?
Whats your AR at currently? Im at about 1.3k buff. You still can upgrade your ammy, glove, ring. Trifecta will help to boost your dps.

As for your the Barber dagger, try get above 2k dps. That will also help you.

For AR you can try to focus on one resistance to maximize OWE.
