As long as you're updating immolation effects, can you change them to only work while in combat?

Ever had a Sunfire Cape and Mobility Boots, walk by a Scuttle Crab, and lose the Mobility effect? I HATE THAT.

With Sunfire being updated and the new Cinderhulk enchantment coming, I think now's a good time to change up the immolation effect so that it only activates while you are attacking or taking damage. This way, those crabs aren't tripping you.
