The only thing I've done that you haven't generally (you've done more overall), is I took item weight and divided by 10 basically to make items lighter. Playing with a gamepad I wanted to reduce additional inventory management to not worry about weight issues.
Another thing, you reduced gold to, but also I dropped the cost of Potions. Since they are one-time use, I was trying to find a price where I think the cost owas worth the one time use. The prices prior were too much that is was a no-brainer not to buy for me.
Right now early game, I set Init -8 to have a mix on who goes first, that is a crazy amount imo, but that is what it took. Not saying this is the best, but was the quickest for me. I'll go back and review what I all have, I know my low levels are 6-8-8-8 init each, so that tells me the baddies early on are around zero.
I'm for anything that limits all the special arrows, scrolls and grenades. It's a cornucopia of too much of a good thing that makes the game lose some tactics. I did bump up AP for arrows, scrolls and grenades. I'm sure I done something with wands, I'd have to relook.
Think about arrows in what could really happen. I was thinking Poison, Water, Fire, Smoke arrows and get rid of the rest. So that having a bow doesn't mean you're a mage. Scrolls with some more requirements are probably a good thing to.
I think we are on the same page, there is a lot you can tweak to make this more of a tactical game, feel more specialized between chars.
