My suggestion would be to work on upping that budget a bit to allow for the purchase of 2x Turned Tooth - it's the best bang for your buck weapon out there right now and you'll be rolling over opponents if you can get your hands on a pair Lens Flare ability at level 50 makes a massive difference as well. What do your pets stats look like, approximately?
