Are all shards equaly powerfull

[High prince of geeks he/him]

In Mistborn we learn that at least ruin and preservation are of equal power. but the Sazed combines them into harmony and he is theoretically twice the strength of an average shard. But in Roshar we can assume the both Cultivation and Honor were shattered, thus the separation of spren as either elemental spren like fire wind and water, and emotional spren, like anger, glory and Honor. It is a big deal that Honor is dead, but nobody seam to make a big deal about cultivation seemingly being shattered as well. And if your going to become a suregbinder you are going to bind with a Honor spren or a Lying spren, or the Stormfather himself, not a flame spren. Infact when These stronger spren weaken they began to resemble simpler spren. Is this because cultivation used more Investor to create the strange planets, or is it because Honor is a bigger part of a whole personality (Andalusian) then the urge to create is(Cultivation). Making a long question simple, were all the shards originally the same strength, or is a shard's strength dependent on how much of Ada;sium that trait originally was?

There is a WoB that all the Shards were about the same strength initially. How they invest themselves in planets diminishes their strength.

We have a WoB that says that Cultivation was not Shattered. Let me See if I can find it. *Starts Searching*

 

EDIT Can't Find it.

The intent of the shard, while not really having any bearing on strength, does make certain things more likely.  For instance, Odium would probably be less likely to invest in humans, leaving him more strength.  Also, the nature of the shard makes an attack on another shard more or less likely.  I can't picture Cultivation going after another shard unprovoked and trying to shatter it.

The intent of the shard, while not really having any bearing on strength, does make certain things more likely. 

 

There is also the fact that certain shards can see further into the future depending on their Intent...

But even so... when Vin became Preservation for that short time, her and Ruin still had a similar amount of power.

Also, when Preservation took the form of the 'mist spirit' in the Hero of Ages, he was weaker and thus allowed Ruin to kill him.

Could it be because Honor presented himself in this same way in order to give Dalinar the visions, that gave Odium the same opening to kill him and shatter the shard

[Jo and the Bush all/any]

Honor was shattered Long before People had the Visions. it seems more likely that the Breaking of the Oathpact Injured Honor in some way, and Let Odium Kill him.
