I agree with a lot of your points regarding how sorc isn't very fun to play. I'm currently close to 70 and I only found a small handful of builds that are semi-viable and fun (not really following any of the "meta" guides though), and decided to switch to rogue for a more interactive game-play.
That said, I did find a couple of uniques for sorc (unfortunately in T3) that changed my playstyle a bit and brought back a lot of power that I formerly lacked, so maybe it's just a matter of getting the right unique to change your perspective on your playstyle.
Regarding the fonts: I've always thought the old-style D2 fonts are really hard to read (you get used to it, but small-caps aren't really designed for legibility) so I really appreciate the change in typefaces.
Edit: I think most of your points regarding quality of life (vendor-spread, FOV, etc) are spot on, and I hope the devs spend some time streamlining some things so we can go back to comparing decimal points as opposed to rubberbanding on horses.
I still think D4 is a pretty decent investment (possibly not full-price decent) but it's hard to assuage the hardcore crowd while also catering to (the millions of) casual players, especially on consoles. That said, it's a pretty good time-waster for a couple hundred hours (at least for me) and when I do put it down eventually, I think I would have gotten my money's worth.
