So lets go with the math for 200:1%, if the +dmg done/-dmg taken/+healing taken increase at the same rate... At 2k thats 100% uptime 10% more damage done, 10% less damage taken, and 10% more healing taken. Tho thats if they all scale equally from the stat. But still have to take into account ALL 3, ALL THE TIME. Sure it feels weak but its always happening, and its happening to pretty much everything.
