Hey! I'm a new to the forums, but a huge fan of the books. So I'd be interested to hear your thoughts about my theory. I haven't seen this on the forum, so sorry if this a repeat and try not to go to hard on me.
A bit of background:
The Honor Spren view themselves as honors order, and were created by honor himself. And the they also see themselves as superior to the other spren. I don't think that this is just them being dicks and/or having a superiority complex.
So presumably he gave his own order the most powerful abilities. But so far all we've seen from Kaladin is the ability to fly and the ability for adhesion. As cool as the superglue ability is, it's noticeably less impressive than the Skybreakers abilities for gravitation and division ( or blowing stuff up), and a bit less useful. Especially since the Windrunners were used as scouts.
So why then did Honor give his order a bad or less useful secondary ability to his own order?
In Oathbringer we saw that Dalinar and the Stormfather can react with Radiants, leveraging the Stormfather and enhance the surges of other Radiants ( example: Shallan making the 3D map, and the Battle of Thaylen City ect...). Also notice that the Bondsmiths also have adhesion, but Bondsmiths have spiritual adhesion whereas the Windrunners have physical adhesion. I don't think that the Windrunners ( honors own order ) and Bondsmiths ( bonded to lesser gods ) sharing the same surge is a coincidence.
Dalinar's Spiritual Adhesion / effect on other knights + Windrunner Physical Adhesion + Stormfather ( Spren of Oaths) = Access to bond more than one order of Spren. ( Either Temporary or Permanent ).
We know that the spren have to have a physical presence( i.e bound physically ) and they have to be bound spiritually spiritually to the person, so mixing everything together it would seem to make sense. The Bondsmith's ability to enchance other surges would be a good gate to making sure that the Windrunners don't go crazy with bonding, and the Stormfather being a sort spren of oaths would make a lot more sense. This is also probably gated under the fourth or fifth oath. It would also clarify why the Windrunners have adhesion, not for the superglue (which is just a side benefit) but instead so when the Windrunner is ready they can continue progressing and becoming more honorable. It would seem like something that Honor would want to do.
Edit: While looking through the coppermind I came by this quote by the Stormfather to Dalinar.
This sounds like foreshadowing to me. It would make sense that Dalinar is the most capable, because he can let windrunners (maybe more) bond more spren and join other orders. And it also fits with the Stormfather because he looks over all the radiant bonding already.
I would like to hear your opinions on my theory!
Also obligatory Kaladin + Jasnah is totally gonna be a thing.
