Imagine a boss does an AoE for 100k. You have a 25m raid with 2 tanks, 6 healers, and 17 dps. The healers must heal up 416,667 damage each, assuming an even split of workload. If you try to run a 40m raid with no additional healers, that increases the healing load to 666,667 healing required from each healer for the exact same mechanic, even if you don't increase the amount of flat damage it deals.
