Unfortunately, Sublime's vintage-mode is very deficient in even the intermediate level Vim bindings. I'll fire it up every week or so, frown after a few minutes, and go back to MacVim.
Yea i'm even running into this and have only been using it for 2 weeks.... sometimes certain things just won't work the same. On the plus side... it's an easy way to dip your toes into the water and get used to normal/insert/visual, which is what I found to be the hardest part.
Fortunately, it's open-source so we have only ourselves to blame and absolutely nothing to complain about.
