Hi, quick question:
Why aren't pull requests made directly on gitlab/somewhere on the site, but instead are sent over email. Even from the human aspect, I think most devs want to track their "ego points" in the form of how many merges they made. 

Or is it just me who is doing it wrong and I should put patches into comments instead?
That depends entirely on the maintainer of the AUR package, there is no "standard" for contributing patches to the maintainer. Some provide a Git{hub,lab,ea} repository for their AUR packages, some don't. Most people who decide to contribute to the maintainer tend to either send the patch by email or put it in a pastebin/gist and put the link in the comments.
