If a 2x2 tree is ever introduced, I'd want to be able to cut it down and possibly have the tree fall and crush you to death, but that's too much to ask for right now.
How about a new tileset. Big tree, that functions as a "wall" tile. More of these in place of the regular trees would fix the mob issues too, as you'll have at least your back covered.
EDIT: So I notice there are more flaming/lightning weapons, but there's no difference between them and the original. As I recall from my weapons comparisons, enchanted weapons are heavier than their normal counterparts, presumably to compensate for the added damage.
EDIT: So I looked it up, it's not the case with the flaming sword, but that is the case with the thunder hammer.
EDIT: So I notice damascus steel comes after adamantine, which in my opinion is rather silly. It should be before/after meteoric steel if you ask me.
