Hello warden mate,
it's a balanced build,not particular mistakes, but it can be improved imo.
I suggest to take Aoe skills..in your build there's no Aoe at all, it's usefull to have it in most situations.
And you didn't take Battle training rubies that reduces pet's skills cooldown, and if you look at your dps meter you can see that Grab's damage is your first source of dps even without those rubies, so it's worth to take them to increase it.
After that.. weapon it's a personal choise, atm i'm using 2hMace and it works good for me, i tried paired but I couldn't reach my usual dps.
Good luck!
Hope this reply can help you
