I would consider a liquifier on the haemy instead of the expensive huskblade.
The reavers work best in increments of 3 for their special weapons. So i would try to add a 6th reaver and perhaps 2x Caltrops, since i think you got decent AT in the ravagers. Swapping them for a splinterborn team in a venom is also an option.
Maybe drop some of the upgrades on the wyches and simply get more wyches instead. Although i probably would swap them for kabalites as they are half of your troop units and they tend to get stuck in combat for several turns if against MEQ leaving out the option for a late game objective grab (just my experience with them often)
