1. I adjust my shutter speed dial with my index finger every time I adjust my shutter speed. I really don't know how much easier it could get for you honestly. It was so natural to me, that I actually had to just check to make sure that's how I do it. Shooting manual is a complete and utter joy with the X-T1.
2. I don't have any problems with metering because I am shooting in manual. When I shoot in AP, I just meter and recompose. Don't really see a problem with this because I've been doing it for so long. Perhaps I don't understand what you are asking for here, but honestly with photography isn't there always a compromise? I shoot raw and recover what I can in post. Decisions about what I'm metering for are made on the spot and I adjust my settings accordingly.
3. Not sure what's going to make you happy here, but we all know Fuji is still fleshing out their lens line up. To compare them to an established DSLR market like Canon or Nikon, or a M43 market with a crap ton of lenses just isn't right. If they didn't have what you wanted and you didn't want to wait, you probably shouldn't have come to Fuji at this time. They are working hard to cover all their bases with lenses, then they'll go back and fill in some holes. Give them time.
4. We all know Fuji is working on this, and have been for quite some time. When they bring a system out, it will meet the demands of their customer base, until then, you'll just have to carry a little bit of extra equipment. I have no doubts that Fuji is striving for something unique and original.
5. Just the way it is. Buy to X-T1's..Problem solved. One battery. One charger...
