By the time they're completely resistant to stun the fights nearly over, assuming the group is optimized for speed. If you're not doing a speed run then min/maxing uptime like this doesn't really matter.

Besides, a lot of AoE's have effects like stun and knockback anyways, so letting them hit you will screw up your DPS even worse.
