Tower Health Regeneration

This is regarding the Inhibitor and Nexus turrets.

I honestly don't have a problem with the change to having no resistances and more health on turrets, but I was wondering if the health regeneration on them has been overlooked. Since the change to health, the regeneration rate has remained the same (1HP/5 on Inhib turrets and 3HP/5 on nexus turrets), but since the turrets have nothing but health and no resistance, this makes the regeneration basically half as effective, since it needs to regenerate more health for the same amount of damage.

If it was intentional, fair enough, but I does make the turret regeneration seem very weak atm.
