I'm another one who would remove the existing healing potion from the general store list, so I'm not really on board with adding more magic items to it.
I'd also be interested in seeing LESS specificity in weapons. I miss the old Normal Sword - whatever the aesthetic design, a culture's primary blade weapon did 1d8 damage. It's how we originally got the longsword and scimitar, which were mechanically pretty much identical until the WorC days began.
But following from there, I'd like to see a return to weapon mastery as well, so a character could develop specific skills and maneuvers with a given weapon, which might appease those who want more differences in design. After all, in the real world you can do things with an axe you can't do with a sword, and vice versa.
