Agree, certain units that have high survivability and can survive off heart crystals or can heal themselves easily (Logan) may not need a healer. But unless you can either deal enough damage to kill the boss fast/be able to spam bb and get a lot of heart crystals, healers are still important as there's always a super strong bb that come out randomly that you need a burst heal.
