Void-holders aren't so great. The only reason to switch into gloves and sacrifice your own personal survivability is if you have a good tank that's managing to keep aggro but is taking a ton of damage and thus needs high heals. The heals from PIs of Dark Matter are far superior to the V4s.

If this isn't the case, then there's no reason not to use a Primed Tempest and shield.

So for engis... yeah... hive weps are better. AND look cooler.
