I have edited the official WotC 5e PDF character sheets for your electronic using pleasure. A lot of work that has gone into various changes, some obvious, some less obvious. the sheet is called "Current Standard" because it's the current standard of character sheet that the general community is...
I'm so glad to hear this! I'm just finishing up the starter set with a group of people, so I've not yet started reading into it. But I'm glad the early reviews are positive so far!
Well I guess the Medicine skill could have some usefulness in some RP situations, possibly if you have proficiency you could leverage doing some cool things with it?
Keep in mind one of the big draws to having scrolls is so that you can copy it down into your book as a Wizard. Not using a spell slot (or needing one) and basically saving a spell for later are just side attractions.
It's really hard to tell at this point. Between the lack of experience we have with 5e and not knowing how the Martials abilities will stack up to Casters. Just remember that there is the slot system that jails a lot of the spells later, so that may help even the playing field.
