You are wrong. Destro/Resto staves skills based on your Max Magicka and Spell Damage.
Light and Heavy attacks scaled of your weapon damage.

EDIT:ALL magicka based skills scaled of Spell Damage and Max Magicka.
ALL stamina based skills scaled of Weapon Damage and Max Stamina.
ALL light, heavy and medium attacks scaled of Weapon Damage.

So, if you see in tooltip Cost X Magicka - spell damage.
Cost X Stamina - Weapon Damage.

What about Light and Heavy Attacks?

As this explanation below I understand that Magicka based skills and Light/Heavy attacks with Staves are all under "Spell Damage"..? Correct?

At least this is what I understood from this:

Edit: Fixed the difference between Light Attacks, Heavy Attacks and Skills.

It was that way BEFORE 1.6 though, hence why you are finding that information
It now works like this though....

•Synergy abilities now scale off your highest stats that are either stamina or magicka based.
•Ultimates and Synergy abilities now always scale of your highest Critical Strike stat instead of just your Spell Critical Strike.
•Abilities that cost magicka will now always scale off your magicka, spell damage, and spell critical strike stats.
•Abilities that cost stamina will now always scale off your stamina, weapon damage, and weapon critical strike stats.

I can't find anything on light/heavy attacks though..
