Did you read the books? I don't say that to indicate "you are not a true fan if you didn't read the books" because fuckin' hell, the last book was a snoozer. But an early and often divergence between the books and the series is "warging". Arya makes one appearance in the entire fourth book - having gone blind in the third - and that's to "warg" around and kick the shit out of her master amongst the Faceless Men. Martin makes it crystal clear that what makes Arya such a ninja badass is her ability to "warg" into whatever random creatures are around long enough to get a good sense of the battleground and then "warg" back to open a can of whoopass.

I think the showrunners took a long, hard look at the source material and said "let's minimize this 'jumping into other bodies' bit as much as possible because it's confusing and off the spine." I also get the sense that they reduced the airtime of the wolves. They were a lot more important in the book. I don't think this was a bad decision - but I think it made the whole "warging" thing confusing and weird. Bran was drawing attention to himself, plain and simple. Which is a pretty weak use of the all-seeing, all-knowing eye but really, battles are often won by the stupidest shit.
