Five-Headed Dragon efffect

Well, I just noticed that this cards effect provided by the DN is the following
"The Fusion Material Monsters for this card are any 5 Dragon-Type monsters. This monster cannot be Special Summoned except by Fusion Summon. This card does not take any Battle Damage, and cannot be destroyed by battle with an EARTH, WATER, FIRE, WIND, or DARK monster. (Battle Damage is still inflicted to players.)"

And actually the effect that is written in the card is this:
"5 Dragon-Type monsters
This monster cannot be Special Summoned except by Fusion Summon. This card cannot be destroyed by battle with an EARTH, WATER, FIRE, WIND, or DARK monster. (Damage calculation is applied normally.)"

Although I prefer the DN's effect, shouldn't it be changed?

They still work the same
If you cannot deal battle damage to a monster, the monster cannot be destroyed by battle. (Doesn't mean the controller of the monster takes no damage)
