Anyway, absorbs spamming can become quite a problem in the future if you take into consideration that a lot of people will be loosing their AS. Without a capping attack, a bureaucrat, for instance, has damage spread out over of pretty much all types. Melee, fire, radiation and cold for pets. Projectile for weapons. Energy for nukes and perks.
None of which can cap through absorbs. You'd literally be able to effectively mitagate thousand of points of damage every few seconds.
