The precise tag is a defining characteristic of a classic "roguish" weapon, technically it means you can use DEX when Hack and Slash with it.
Default weapons list is very short in Dungeon World, and only two weapons from it has the "precise" tag. By contrast with D&D, a DW dagger is not precise. This oddity was noticed on the PbtA forums:
It appears to me that the intent is to make "precise" a rare tag, via cost. It costs 25 coin for a rapier (the cheapest precise weapon), and 8 coins for a short sword/axe/mace/etc. The only difference is the precise tag.
I wonder was in intentional, or is it just an oversight. There was no official answer tho. Since designers' reasons questions are off-topic here, I'd ask it another way. In terms of game balance, does adding 'precise' tag to daggers break anything? (by "balance" I mean that game should feel fair, and nobody steals the spotlight from any PC) Should the DM tweak other tags, consequences or price accordingly? How exactly?
Bonus points for those who tried this in their games.
Double bonus points if you actually know what the developer's intent was.
