I currently try to get my health as close to exactly 20k as possible as a sort of deterrent when I'm solo guarding a node or door.
Now I'm sort of having second thoughts and considering to go the pure DPS root which would drop my health 600 points and increase my power from 570 to 766 (+30 damage, +30 bonus damage.)
i prefer power over health as a dps. If a team wants me dead Ill get dead no matter how much health i have. So I'd rather kill whats in front of me quicker. Right now Im sitting at 918 bonus damage (have stacked 1025 power)
