Are 310 helicopter losses in Ukraine that high? I don't think so. Russia has lost =~ 3K tanks. That's a 10:1 ratio for tank:helicopter, is that high?
Helicopters' role may change. They would be ideal drone operator platforms - they already have a weapons operator in a back seat. The right cannon / loadout could take out small drones. Collaborative Combat Aircraft (CCA) style wingmen would work with quadcopters for helicopters. They could expand the sensory capability to avoid surface to air threats.
