A few thoughts.
daggers or bows that inflict poison with DoT.
Poison daggers are in. Any melee weapon can be poison dot with a +poison item equipped, but there are also specifically named toxic daggers. Poision bows are a nice concept, but very hard to balance with kiting issues. It's already a challenge to keep bowmen balanced.
High level versions of the leather armours. Perhaps give initiative bonus, or adds lightning damage to attacks?
Yes. I would like to see an upgrade path for lightly armored troops, rather than one upgrade path for all armor.
AoE versions of the mage staves. Heaps less damage, but does an area of effect (cone, or 3x2 area or something)
Not at the expense of spells, IMO. Magic staves already do very low damage, at least until the second tier, which comes late. Anything better, and you should have to spend mana, IMO.
High level staff weapons. Maybe give higher dodge, or elemental damage?
There are staff weapons that do melee elemental damage. Ranged staves do elemental damage, but should not be any more powerful than they already are, IMO. Again, it would be at the expense of casting magic. Anything more powerful than an average bow, and you should have to spend mana.
Ring of magic missiles. Initiative nerf, with the ability to cast a magic missile. does equivalent to a mid rang sword damage as ordinary damage (no element).
I wanna cast... Magic Missle!
